slackware 10.1 mod ruby make error

Hy list,

I'm installing modruby on a slackware 10.1
but a compilation error happens:

$ make
gcc -O2 -march=i686 -mtune=i686  -fPIC -Wall -DLINUX=22 -DHAVE_SET_DUMPABLE 
-DUSE_HSREGEX -DEAPI -I. -I/usr/lib/ruby/1.8/i686-linux -I/usr/include/apache   
-c mod_ruby.c
cc1: error: invalid option `tune=i686'
make: *** [mod_ruby.o] Error 1


can you help me ? 

tnx
