Should work as well. I'll look into that for completeness.

Regarding the Compaq tools, you should not need to change any of the search-paths.
They link the libaries from their respective dirs in /usr/lib/compaq to /usr/lib.

ldconfig considers /lib and /usr/lib as "trusted paths" and searches them anyway. No need
to put them in /etc/ld.so.conf ( which is a bit crappy IMHO anyway - but that's another story ).
Especially, you should avoid putting version-specific paths in there, like the line
containing gcc-lib below.

Ok. libgcc ( which appears to be missing ) is in /usr/lib/gcc-lib/alpha-linux/2.95.2/libgcc.a

That tells two stories.
1. It's an ar(1) archive. Not a shared object. ldconfig, ld.so.conf and friends have absolutely
    nothing to do with it. The linker has to find it at compile-time ( better: link-time ).
    Everything you do with ldconfig and friends, it manipulating paths, were the dynamic
    linker finds shared objects at run-time.
2. The file comp.config in /usr/lib/compaq/ccc*/*/bin *must* contain the line
    -L/usr/lib/gcc-lib/alpha-linux/2.95.2

The second point is of importance. The switch "-L<something>" tells the compiler driver
 ( ccc ) to pass the path following -L to the linker.

The best would be, to show the contents of comp.config, you have.
