> You can see from "port variants atlas" that's not so. The pseudoport syntax "variants:clang33" means "ports whose list of variants *contains* the string clang33". Pseudoport syntax uses regular expressions. Unfortunately, the match is made over the entire list of variants, not each individual variant, so if you want an exact variant name match, you have to jump through hoops:
> $ port echo 'variants:(^| )clang33($| )'
Thanks. That is a little counter intuitive, I have to say.
Any reason why atlas uses 'mpclangXY' for the variant name, where as other ports seem to have standardised on clangXY, to match gccXY ?
