Re: [PATCH] Detect the default libpath on aix (to fix MPI support!)

Yes I know this is normal when using gcc.

But it is rather ugly, and might be a small performance hit,
as you have to search a number of directories that will never
contain any useful shared libraries.

I wonder if this was the reason the -blibpath was introduced in
the first place?
