postgres 8.3.8 and Solaris 10 problems?

So I compiled postgres with Solaris 10 and have problems running it.

# ./pg_ctl
ld.so.1: pg_ctl: fatal: relocation error: R_AMD64_32: file
/usr/local/postgres64/lib/libpq.so.5: symbol (unknown): value

What am I missing???

Here's my environment.

Solaris 10 x86_64 with postgres 8.3.8 and openssl 98k using gcc version
3.4.3 (csl-sol210-3_4-branch+sol_rpath)
, sunstudio12.1 and GNU Make 3.80

Thanks!
