[Halld-offline] hdgeant on centos 5.3

[David Lawrence]

Hi Richard,

    I can report that I have successfully built and run hdgeant on the 
new 64-bit nodes and have run several farm jobs using single track 
events from the built-in particle gun on them without any problems.

    The problem you may be referring to was one Beni reported at the 
July 29th Software meeting: (see 
http://www.jlab.org/Hall-D/software/wiki/index.php/July_29%2C_2009_Software) 
As I understand it, Beni committed a patch that he considered a 
temporary solution (see Action Items from August 12th meeting). Others 
can report if this particular bug is holding them up, but I'm not aware 
of any grumblings.

Mark has also been working on a Fedora 11 build which I think he has now 
completed. He can comment as to whether there were any problems running 
hdgeant under that OS.


Regards,
-David
