Dear FreeCAD developers, users.

I installed FreeCAD on Fedora 16 using yum install freecad.i686 command.
It was successfully installed, but some workbenches did not work until I manually installed PyQt4 and PyQt4-devel with correspondent yum commands.
I and any other ordinary user would expect that those two packages required for FreeCAD should have been installed as dependencies by yum.
Hope this information will be useful otherwise I am sorry for bothering you.

Thank you and best regards,
