Installing GNU-Prolog on Mac OS X, Intel chips

Hi all,
	I had previously send a message about an installation problem and  
your help then was very usefull,
I have a new problem : is there a way to make GNU-prolog work on the  
knew Intel-Macs ?
I managed to compile glpc but the compiler would'nt compile .pl file.

The failed compilation outputs this kind of message :
"...
/var/tmp/gplcaf4aVd.s:14478:no such 386 instruction: `addi'
/var/tmp/gplcaf4aVd.s:14479:no such 386 instruction: `blr'

/var/tmp/gplcaf4aVd.s:14492:no such 386 instruction: `blr'
compilation failed"

Maybe a workaround would be to annonce that the machine is a i386 GNU/ 
linux, but i don't know how to test this
