crle and missing libusb.so.1 library

Today I have installed SpamAssassin from a tar.gz archive on Solaris 10 10/09.
Though everything looked fine I faced the problem with invocation of sa-update - SpamAssassin rules updater.

$ sa-update
ld.so.1: gpg: fatal: libusb.so.1: open failed: No such file or directory
Killed
ld.so.1: gpg: fatal: libusb.so.1: open failed: No such file or directory
Killed
error: GPG validation failed!
The update downloaded successfully, but the GPG signature verification
failed.
channel: GPG validation failed, channel failed
$ gpg
ld.so.1: gpg: fatal: libusb.so.1: open failed: No such file or directory
Killed

(gnupg has been installed from a package from sunfreeware.com, but it was not a problem)

Quick truss session:

# truss gpg

find lookup:

# find /usr -name libusb.so.1
/usr/sfw/lib/libusb.so.1

...and I had to change the default library path.
The tool - crle - runtime linking environment configurator, was taken as the only fair solution.
Do not want to reproduce the manual pages, so, below is the syntax I had used.
Checking the current options:

# crle

Configuration file [version 4]: /var/ld/ld.config  
  Default Library Path (ELF):   /lib:/usr/lib  (system default)
  Trusted Directories (ELF):    /usr/lib/secure:/opt/sun/comms/calendar/SUNWics5/cal/lib

Command line:
  crle -c /var/ld/ld.config -s /usr/lib/secure:/opt/sun/comms/calendar/SUNWics5/cal/lib

Complementation of default library path:

# crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/sfw/lib -s /usr/lib/secure:/opt/sun/comms/calendar/SUNWics5/cal/lib

[CHECK]
# crle
Configuration file [version 4]: /var/ld/ld.config  
  Default Library Path (ELF):   /lib:/usr/lib:/usr/sfw/lib
  Trusted Directories (ELF):    /usr/lib/secure:/opt/sun/comms/calendar/SUNWics5/cal/lib

Command line:
  crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/sfw/lib -s /usr/lib/secure:/opt/sun/comms/calendar/SUNWics5/cal/lib
# exit
$ gpg

$

Final notes
The syntax being used could be shortened to a form of:

# crle -u -l /usr/sfw/lib

where -u stands for existing configuration (file /var/ld/ld.config) update.
But be aware that by omitting the -u argument you turn your box into soldered fish tin, until you turn the other directories to the default path.

# crle -l /usr/sfw/lib
# init
ld.so.1: init: fatal: libpam.so.1: open failed: No such file or directory
Killed
# crle -u -l /lib -l /usr/lib -l /usr/sfw/lib

svclog

Everytime I have to check the SMF log file quickly I suffer.
I suffer in due to lack of simple method which I would provide you today with.

C'n'P:

#!/usr/bin/ksh
#------------------------------------
# svclog
#  ...run for your logs
#====================================
# author: Marcin Wisnios
# e-mail: wisnios at wisnios dot com
#------------------------------------

svcs $1 > /dev/null 2>&1
if [ $? -eq 1 ]; then
        echo "No match."
        exit
fi

if [ ! -z $1 ]; then
        LOG=$(svcs -l $1 | sed 's/logfile[ ]*\(.*\)/\1/p;d')
        echo "\n\t\t${LOG}\n"
else
        echo "Usage: $0 FMRI [n]"
        echo "n - number of lines to display"
        exit
fi

if [ ! -z $2 ]; then
        tail -$2 ${LOG}
else
        tail -f ${LOG}
fi

Save as, for ex. /usr/local/bin/svclog and... run for your logs:

# svclog ds 3

                /var/svc/log/application-sun-ds:default.log
