That doesn't work because it's missing the Epoch. ">= 1:4" would work, but 
it's better to use the virtual qt4-devel Provides, which is backwards-
compatible with EPEL 5 (which had an actual qt4-devel package), which will 
keep working in the future when Qt 5 will be the default and which avoids 
the pesky Epoch.
