Is this a gem with a extension? Or is just pure-ruby code?

"--platform=x86-linux" should work, the same for "x86-mingw32" or
"x86-mswin32-60" under Windows.

Originally the platforms are indications of binaries being carried and
bundled in the gem, not under which platform the gem should work.

As example, the "session" gem is marked as "ruby", but it only works
on POSIX OS. Because of that, developer will need to release one gem
for x86-linux, x86_64-linux, x86-darwin and ppc-darwin.

I guess that a condition in the library will be enough.
