No I feel ashamed that although I was lobbying for gcc BR, I never used it in my packages. So thank you František for doing so (I assume that you were forced to do so due to gcc missing in buildroot, right?).

Now I just wonder, wouldn't it be better to add these requires into ruby-devel? Although one can BR: ruby-devel just because of the macros, so this would be unnecessary.

So my other idea is to modify gem2rpm to add the requires whenever the gem has binary extension. There might be false positives as well, but one should review the otput of gem2rpm, so it is possible to remove the BR in case it is not required.

Any comments?
