Comment (by rmottola):

 the issue... is worse. I uninstalled all python versions, install cmake
 and first python gets pulled in, built and installed (and has fine shared
 objects) then it does the same process again, but in +universal (it is a
 64bit machine and I enabled that) and now the modules are broken.
 When I did the test you asked, I did not add +universal...

 now, scrolling back in the console I see messages like this:

 and this is repeated the same for every .so
