I personally hate LD_LIBRARY_PATH. Too fragile and volatile.
(It's the right thing for a devel environemt).  But I know
it's sometimes too tedious to find something better ;)

So why not choose a different soname for conflicting libraries,
e.g., libfoo.so.1forte or libfoo-forte.so.1.

I've not know for solaris 8 but maybe there also other
alternatives some OS allow ...
	o for not-setuid/gid
	  programs to use environment vars in rpath.
	  (can env var also be used in *.la files??)
	o ivers games:  If a lib in
	  /path/soname has the same SONAME but not same
	  ivers,  OS ignores the lib and looks in
	  /path/ivers/soname

IMHO libfoo.so.1forte is 'the right thing'.  One only has
to find a include + lib dir that's only search by forte
and not by gcc during compile time.  Then identical .so
and .h files  can coexist on the same system without
conflict and compiler finds the right versions.

  To me vi is Zen.  To use vi is to practice zen. Every command is
  a koan. Profound to the user, unintelligible to the uninitiated.
  You discover truth everytime you use it.
