SDL-devel requires alsa-lib-devel

Foo-devel requires alsa-lib-devel

There's no direct relation between SDL-devel and Foo-devel.

yum remove alsa-lib-devel removes both SDL-devel Foo-devel, since they
both required alsa-lib-devel. yum install SDL-devel only install
SDL-devel and its requirements, which do not include Foo-devel.
