patch to suppress deprecated warnings from python2.6

[goodell]

According to Ralph Butler, these warnings were introduced in python2.6 to start herding everyone towards python 3.0 compliance. Other than an unsightly warning message, they don't interfere with the actual operation of the code. So I've attached a patch that should suppress the warnings for now. Give it a try and let me know if that solves your problem.

In the long run we'll either need to update mpd to use the new modules or we'll have to deprecate mpd in favor of hydra, once it's ready for production use.

Committed as r3726. Resolving as fixed for now.

Scott, please let us know if this solves your problem.

Hi Dave,

I passed the patch on to the customer. He ran into a separate issue
where ROMIO failed to compile.

FYI, the IBM XL compilers do not like --version. Every time configure
tries to use it to determine the compiler's version, xlc and xlf dump
their man pages. :-P  His config.log was 4 MBs.

He has switched to Open-MPI for the time being.

Thanks,

Scott

What was the ROMIO error?

I have attached his logs.

FYI, similar warning suppression changes were made to the other mpd scripts in r4923.
