>Description:
Hi,

Running "pkg_which" as a non-root user hits a segfault resulting in a core dump from ruby. This happens even when the package database has been rebuilt with "pkgdb -fu", and PORTS_DBDRIVER is set to bdb1_hash or dbm_hash (got this from freshports.org). Here is copy of the session executing pkg_which:

---------------------------------------------------------
[amar at dexter ~]$ pkg_which bash
The pkgdb must be updated.  Please run 'pkgdb -u' as root.
[amar at dexter ~]$ sudo pkgdb -fu

It works fine for root though

---------------------------------------------------------
dexter# whoami
root
dexter# pkg_which bash
bash-3.1.17
dexter# 
---------------------------------------------------------

Though this thing is documented in the pkg_which manpage, I find two inconsistencies here:
1. Segfault is hit even after "pkgdb -fu" is done.
2. It works fine for root user.

Thanks!

Best,
Amarendra
