if you got the rpm from www.rpmfind.net
it lists which distro it's intended for.
If you got it somewhere else I dunno, most should work.
A little diddy on rpm's... Unless it's designed for your specific distro I would not use it.
Get the tar ball (.tar.gz or .b2z) file and install using ./configure, make and make install.
As for installing rpm's always do it in a console window (imho) using "rpm -ivh filename.rpm" that way works great.
Oh... and if that does not help give a yell back.
