I think I found it: The working version of mwrank.so is compiled with g ++, while the non-working version is compiled with gcc. I would guess on Gary's and many other systems gcc does the right thing, but on your system it doesn't link to the C++ code of eclib. mwrank.c is a pure C wrapper for eclib's C++ code, so I guess in the end the linker is the key player here. Switching the mwrank.so extension to be build with C+ + should fix the issue.
