This might be completely unhelpful, but I'll post it anyway just in case 
it's perversely relevant.

I had FPC running on SPARC under Solaris 10, and investigated getting it 
running on Solaris 8. The problem turned out to be that a system library 
(let's say it was libc.so, but I'm working from memory) was symlinked to 
libc.so.2 on Solaris 10 but libc.so.1 on Solaris 8, and the linking 
stage was resolving the symlink rather than leaving it until the program 
was run.

In the end I did something like copying libc.so.2 to libc.so.1 and 
changing libc.so to point to the latter. I built FPC (possibly just 
ppcsparc) and copied that to the v8 system, then restored the original 
symlink. At that point FPC ran OK on v8.
