Description of problem:
The /usr/sbin/osipsconsole script in the main opensips RPM requires programs which are not listed in the Requires section of the package and therefore do not get installed along with the script.

Version-Release number of selected component (if applicable):
opensips-1.7.2-2.el5

How reproducible:
Always

Steps to Reproduce:
1.  Install opensips main package
2.  Run /usr/sbin/osipsconsole
3.  Install DB specific sub-packages (-dbberkeley or -mysql)
4.  Run /usr/sbin/osipsconsole
  
Actual results:
which: no md5 in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no mysql in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
Error: 'mysql' tool not found: set MYSQL variable to correct tool pathwhich: no db_dump in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.4_dump in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.5_dump in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.6_dump in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db_load in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.4_load in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.5_load in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)
which: no db4.6_load in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/root/bin)

Thank you for flying Opensips!!

Expected results:
Install proper requirements (based on subpackage installed? ie: -dbberkely or -mysql)
No errors running the "which" commands (redirect STDERR to /dev/null)

Additional info:
The script does not redirect STDERR so the failures are written to the console:
