Well, not really, since it just assumes gcc is installed, which is not such a weird assumption in Gentoo (Linux). It's just that you are on the only arch that doesn't use GCC, which is a big deal of the difficulty of getting it working.
What can I say - I strive to be different :) ... and this bug wasn't filed accusitively - more just as an FYI. (And the problem problem lies with 'version_is_at_least' now I look at it: that test probably shouldn't pass for it to trip up on built_with_use in the first place. Actually, now I look again, version_is_at_least may be reading 7.4.4 from the MIPSpro output and (correctly) deciding that this is, indeed, at_least 4.3!) Does Gentoo proper not have *any* GCC alternatives? Something like tinycc for embedded systems? Or is there some alias/virtual in place for any such to appear as gcc (and would it be of any use under prefix to prevent portage from complaining about GCC not being present on IRIX)? How does prefix on Sun with the Sun Studio compilers cope with this?
This is checked via tc-has-openmp() these days, which compiles a little program in order to determine whether or not openmp is available.
