Dears,
After successful installation of alps-2.0.2 on my desktop (Scientific Linux 6.1) I moved to the cluster with RedHat5(el5) with gcc 4.1.2 and python 2.4.3 . Make produced error:

Linking CXX executable compactrun

collect2: ld returned 1 exit status
make[2]: *** [tool/compactrun] Error 1
make[1]: *** [tool/CMakeFiles/compactrun.dir/all] Error 2
make: *** [all] Error 2

Is the above to the old compiler or there something else?
