Ok so on a test VM which is from a minimal base and epel enabled... xterm comes from base ImageMagick comes from base libXpm comes from base You might want to check your repos as there is nothing other then CentOS6 base required in your list... From epel on a minimal install fribidi, libstroke, perl-File-BaseDir, perl-File-DesktopEntry, perl-File-MimeInfo, xlockmore are pulled in. Everything else is from EL6 repos....

Pretty sure my test C6 VM only has epel enabled... I'll do a double check when I get in the office and update with a new comment.

fedup of F21 server install to F22 beta TC5 server worked after installing this for me
