I don't really know how many people have run into this, but I'm putting
what I had to do forward. Hopefully it will help. Specifically, this is
for an EV56 system, using the compaq compiler. 

What I've noticed, is that the configure scripts don't have a catch to
give the correct flags on a linux system running a compiler other than
gcc. Since this system fails all of the checks (is not running solaris
for example), it defaults to not building shared libraries with the
compiler. 

This was a little annoying. So I made an addition to libtool.eclass, it
should be attached to this message.

This is not really getting to the heart of the problem, I haven't had
time to dig that far. If someone has a more elegant solution, I am all
ears. Suffice to say, this is what has worked for me, maybe it will help
someone else.

There is an effort in progress to enable compiler "profiles" (for want of
a better word) that will enable people to choose their compiler much the
same way that gcc-config sets the gcc version.

Check bugs.gentoo.org, there are patches or partial solutions in there
somewhere. (there could also be a masked version of gcc/gcc-config in
portag, check in packages.mask)

I'm sure your contributions would be welcomed by the devs that are
undertaking this.
