Obspy installation on RHEL and EPD 7.3

Hi all,
I have difficulties to install Obspy 0.9.2 on our cluster, while version 0.9.0 installed fine. It seems to be due to the fortran part (again). I was not aware of any important changes here. Anybody has a clue what might be going on here?

uname -a
Linux tesla 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

Thanks!
