Hello, I've been using ALPS for a while (mostly the CT-HYB solver). Now we are trying to compile ALPS from source on a larger (Red Hat) cluster and we've encountered an issue. The installation proceeds mostly fine (except that test 137 python_mcanalyze fails at "make test"), but the cthyb module is missing from pyalps. i.e.: import pyalps works, but import pyalps.cthyb produces ImportError: No module named cthyb We also noticed that the hybridization binary is missing from install/bin The same installation protocol worked on another machine, so we are somewhat mystified. Where could the problem be? We are using ALPS version 2.2.0b4 alps-2.2.b4-src-with-boost.tar.gz <http://alps.comp-phys.org/static/software/releases/alps-2.2.b4-src-with-boost.tar.gz> and basically follow the instructions here: http://alps.comp-phys.org/mediawiki/index.php/Building_ALPS_from_source#Buil... Best regards, Petar
