[yt-users] undefined symbol: _intel_fast_memcpy

[Jean-Claude Passy]

Hi Jeff,

sorry I am little bit lost. Python seems to work fine even if the intel 
module is loaded:

###########################################################
[11:37:45] seawolf1:$ module load intel/11.0.074
[11:37:49] seawolf1:$ which python2.6
~/yt-x86_64/bin/python2.6
[11:37:59] seawolf1:$ python2.6
Python 2.6.3 (r263:75183, Apr 14 2010, 08:48:56)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

###########################################################

How do I know which compiler I used to build yt ? I can't find it in the 
install script.
Thanks,

JC
