Try reading the README's in each tarball ;-)

FYI, it installs pretty much painlessly under Mandrake 10.*, FC2 and FC3

FYI, there are RPM's for wxPython.
See http://www.wxpython.org/download.php#binaries

Packaging GNU Radio into RPM's would be great!

You can install both single and double precision.  If you like,
you can install the single precision in /usr/local and keep it out of
yum's way.  Or better yet, get somebody to fix the upstream RPM so
they build and install both versions.

Being on the list is pretty much essential for using the USRP and GNU Radio...

This all sounds like good fun!
