./InstallGNUstep question

[Bryan Rehbein]

I have been working on trying to get GNUstep to compile and install on 
OpenBSD 3.8, so far I have been successful at compiling and installing.  
Now I haven't gone through and tested anything as of yet.  I have a 
question about the install scripts, where are they actually looking for 
the libpng header files.  I installed libpng from a OpenBSD package 
(v1.2.8) and that package puts the header files under 
/usr/local/include/libpng/, it seems as if the install/compile scripts 
were looking in /usr/local/include/ and were unable to find the header 
files, thus compile was ending on GNUstep gui.  I placed a sym link in 
/usr/local/include/ for both of the header files and everything finished 
compiling.  I'm just trying to figure out where this little error is 
coming into play.  Did the maintainer of the PNG package put the header 
files in a non-standard place, or is GNUstep looking for it someplace 
non-standard?

Oh, another thing, can you get the GNUstep.sh script to play nice with 
tcsh?  It works beautifully under bash, but tcsh I get:
piro:squallbsr {10} source 
/usr/local/GNUstep/System/Library/Makefiles/GNUstep.sh
ZSH_VERSION: Undefined variable.
piro:squallbsr {11}
