[Serusers] Problems compiling on Solaris 10 x86

Hi all, I would like to try out SER in my network, but am running into problems with compiling it. I running Solaris 10 x86 32bit, with MySQL 5.0.51 installed and running. I've installed all the pre-reqs listed in the INSTALL file, using make 3.81, and gcc 3.4.6. But when I try to compile using: make group_include="standard" all, I get make error: Assembler: udomain.c "/var/tmp//cczTJdew.s", line 3006 : Illegal mnemonic Near line: " ffreep %st(0)" "/var/tmp//cczTJdew.s", line 3006 : Syntax error Near line: " ffreep %st(0)" make[1]: *** [udomain.o] Error 1 make[1]: Leaving directory `/tmp/programs/ser-2.0.0-rc1/modules/usrloc' I tried googling and looking at the mail list archives but couldn't find much info... Can someone please give me a hand? Very much appreciated. Thanks, Ben
