Not really - the guidelines say, that you should use %prep for the gem install command (which basically unpacks the gem into a proper directory structure) and %install to place the files precisely where we need to under %{buildroot}.

I think that it wouldn't make much sense - the install command in %prep does everything we need - unpacks the gem into a proper directory structure (and compiles the binary extension, if any). This way you can use %prep to apply patches and then, if you need to recompile a patched C extension (if any), the %build section is the place to do it. Otherwise, I see no point in using %build section with rubygems.

Yes, well, if you have nothing to compile, it makes perfect sense to leave the %build section empty, doesn't it? And you use %prep to unpack the gem and %install to place it into a proper directory structure. What's wrong with that? I think that it works exactly as it should.

Bohuslav.
