>Description:
All GNUStep applications like for example GNUMail or Project Center crash 
complaining about the gnustep-back bundle:


The problem seems to be that the gnustep-back bundle is linked against the 
wrong libraries (as I found out on osdir.com)
"The problem is the -R/usr/X11R7/lib flag on the command line. This option is 
understood by NetBSD's gcc and it ends up as an *initial* -R flag to the 
linker, whereas the -Wl,-R<dir> options stay in their place. That means that 
the broken libpixman will be found before the right one in /usr/pkg/lib. 
Unfortunately, the -R flag is added automatically by autoconf when testing for 
the X libraries, so we cannot get rid of it."
>How-To-Repeat:
pkg_add -v GNUMail
>Fix:
After a long search I found that someone was able to fix it:
compile gnustep-back with  ./configure LDFLAGS=-R/usr/pkg/lib

Here is the thread where they describe it:
http://osdir.com/ml/discuss-gnustep-gnu/2010-11/msg00147.html

however I wasn't able to change the Makefiles or patches to bring the success. 
Adding simply LDFLAGS=-R/usr/pkg/lib under the CONFIGURE+= into the pkgsrc 
Makefile didn't help.
