>Description:
I decided to try the libart backend for gnustep.  I did the following steps:
1) added WITH_GNUSTEP_LIBART=yes to my /etc/make.conf
2) ran "portupgrade -fr gnustep-base"

now, if i try to run anything gnustep, i get the following error (for example):
bgruber at calvin:~>openapp GNUMail
2003-08-23 19:13:13.704 GNUMail[10515] No local time zone specified.
2003-08-23 19:13:13.704 GNUMail[10515] Using time zone with absolute offset 0.
2003-08-23 19:13:13.704 GNUMail[10515] NSApplication.m:191  Assertion failed in initialize_gnustep_backend.  Unable to find backend libgnustep-back.bundle
/usr/local/GNUstep/Local/Applications/GNUMail.app/ix86/freebsd/gnu-gnu-gnu/GNUMail: Uncaught exception NSInternalInconsistencyException, reason: NSApplication.m:191  Assertion failed in initialize_gnustep_backend.  Unable to find backend libgnustep-back.bundle

Analyzing the situation, I found that indeed libgnustep-back.bundles had been replaced with libgnustep-art.bundle.  On a hunch, i tried symlinking libgnustep-back.bundle to libgnustep-art.bundle.  Now I get this error instead:
bgruber at calvin:~>openapp GNUMail
2003-08-23 19:17:38.175 GNUMail[10604] No local time zone specified.
2003-08-23 19:17:38.175 GNUMail[10604] Using time zone with absolute offset 0.
2003-08-23 19:17:38.174 GNUMail[10604] No fonts found!

this last bit seems like a libart problem maybe, but i'm not sure.  all my gnome applications for example, which depend on libart, work fine.  I've tried this with GNUStep and Gorm.
>How-To-Repeat:
set "WITH_GNUSTEP_LIBART=yes" in make.conf.  Rebuild gnustep applications.  Try to run them.
