CentOS-5.2
A Fedora 8 package can be found here
http://rpmfind.net/linux/rpm2html/search.php?query=qt4
e.g. qt4-4.4.3-1.fc8.x86_64.rpm
The x86 package is OK in my CentOS-5.2, so I'd guess,
the x86_64.rpm is too.
The devel package
http://rpmfind.net/linux/rpm2html/se...&system=&arch=
is a bigger problem, as it will need lots of dependencies.
It is easy ? to compile qt4, might be the way to get all
files, if required.
