_MPIU_Thread_CS_enter_lockname_recursive_impl_ not supported

When trying to link ISSM, I get the following error with my MPI.

I am on Mac OSX Lion 10.7.4

ld: targeted OS version does not support use of thread local variables in _MPIU_Thread_CS_enter_lockname_recursive_impl_ for architecture x86_64

To resolve this issue, mpich needs to be reconfigured with the flag:

ac_cv_tls=none

To do so:

open install-3.0-macosx64.sh

On the line that says: ./configure \

Change it to: ./configure ac_cv_tls=none \

Re-install mpich and then recompile ISSM.
