Hey Scooter,

Thanks for your talk on on Wednesday.  Much fun.

Had a quick look at PDL on the tram this morning and it looks pretty 
cool.  I'm quite keen to try this out for graphing financial data.

Installs perfectly on Fedora 17

	yum install perl-PDL

Bang! Get the full kit, so its probably possible on RHEL.

Did a quick try on CentOS 6. Yup, fine. Did a quick try on CentOS 5 and 
got various dependency errors.  Looks like there are only 3 packages 
with genuine issues:

     libXft-2.1.10-1.1.x86_64 from base
     libXrender-0.9.1-3.1.x86_64 from base
     perl-Tk-804.029-1.el5.rf.x86_64 from rpmforge

The perl-PDL package seems to be coming from RPMForge so a gather its a 
partial back port.  I'd be talking to those guys to get it fixed, though 
it may not be technically feasible: libXft and libXrender are probably 
required by a lot of other packages and upgrading them to the required 
versions may break too many other parts of the system.  May be _easier_ 
to move to RHEL6 than to try to solve a very complicated dependency 
problem at that the RHEL5 level.

By the way, as I learned recently from a conversation with a MPM member 
and subsequence investigations, the redhat bug tracker is not really 
being tracked by redhat any more. If you want redhat response you have 
to use the official support channel. If you are using CentOS, just email 
the CentOS list: there are people there with full RHEL subscriptions 
that are more than willing to raise the issue on your behalf.

Happy Hacking!
