Issues using garnome on Solaris x86

[Carson Gaspar <carson+garnome taltos org>]

I couldn't find any binary packages of Gnome 2.4 for Solaris x86, so I 
decided to grab gargnome & try to build it myself. So far, I've run into 
the following issues with the build system:

- The Makefiles assume a POSIX shell is being used by default

Setting SHELL = /bin/bash in gar.conf.mk fixed this problem

- The Makefiles assume tar is GNU tar (or at least something better than 
Solaris' tar, which can't extract the tarballs)

Changed tar to $(TAR) in gar.lib.mk, set TAR = gtar in gar.conf.mk

- The Makefiles assume patch is GNU patch

Changed patch in gar.lib.mk to $(PATCH), set PATCH = gpatch in gar.conf.mk

- gnome/libxml2/files/buildDocBookCatalog assumes GNU find (uses -iname)

I just made sure GNU find was fist in my path. It is trivial to change the 
pattern used to be "[Ii][Ss][Oo]*[Aa][Mm][Ss][Bb].[Ee][Nn][Tt]" if you 
really need it to be case insensitive.

- Some Makefiles assume install is BSD install (noticed in 
gnome/ttf-bitstream-vera/Makefile)

I just made sure /usr/ucb/install was the install found, but the Makefile 
should be changed to use $(INSTALL), and INSTALL set in gar.conf.mk.

- A general GNOME problem is that all the *-config systems fail to set 
RPATH in their --libs output

I've just manually hacked the *.pc files and *-config scripts to include a 
-R for each -L. I really wish the GNOME folks didn't assume everyone will 
hack their ld.so config or set LD_LIBRARY_PATH...

I'm still not done building the beast - if I find any other issues, I'll 
let folks know.
