Dear all, especially Tom T and Laurie Betts: I've recently installed phenix-dev-1084 and Rosetta 3.4 on RHEL 6.2. No problem. When I test the rosetta commands with phenix_regression.wizards.test_command_line_rosetta_quick, the first 12 of 39 tests succeed but test_prerefine fails and the process aborts. This is the error in the log file: /csb/soft/Linux64/share/rosetta3.4/rosetta_source/bin/mr_protocols.default.linuxgccrelease: error while loading shared libraries: libdevel.so: cannot open shared object file: No such file or directory libdevel.so exists, in the right place I venture to say: ls -l /csb/soft/Linux64/share/rosetta3.4/rosetta_source/build/src/release/linux/2.6/64/x86/gcc/4.4/libdevel.so -rwxr-xr-x. 1 csbadmin csb 6437 Jun 23 18:44 /csb/soft/Linux64/share/rosetta3.4/rosetta_source/build/src/release/linux/2.6/64/x86/gcc/4.4/libdevel.so Besides the tests failing, the actual mr_rosetta run fails as well, as one would expect, with the same "missing library" error. This problem has been reported before (http://www.phenix-online.org/pipermail/phenixbb/2011-May/017157.html), but I can't find a solution. Is there one? Thanks. Andreas
