Coding model error compiling mod_perl.so

When compiling mod_perl.so, I get:

ld: fatal: relocation error: R_SPARC_H44: file /dsk01/apache/app/build2064/perl-5.12.2/lib/5.12.2/sun4-solaris-thread-multi-64/CORE/libperl.a(op.o): symbol <unknown>: relocations based on the ABS44 coding model can not be used in building a shared object.

I'm using gccfss:

sparc-sun-solaris2.10-gcc (GCC) 4.3.3 (20091210) (gccfss)

My  compile options are:

CC="gcc -m64 -mcpu=niagara2 -O3"

I tried adding "-fPIC", but that didn't help. I think the coding model error may be a false flag.

I'm guessing my perl needs to be rebuilt with different compile options? I was thinking I should be able to use elfdump to see if this is the case, but I'm not sure how.

Any help would be appreciated.

Cheers,

Ryan
