Hi Michael, A) f77lapack & blas refer to the libraries that I came with my OSX (or rather my Xcode version). These live under $find /usr/lib \( -iname "*lapack*" -or -iname "*blas*" \) /usr/lib/libblas.dylib /usr/lib/libcblas.dylib /usr/lib/libclapack.dylib /usr/lib/libf77lapack.dylib /usr/lib/liblapack.dylib Initially I completely forgot I already had them installed and that's why I pulled the fink install lapack. However, I double-checked the fink libs and, you were right, these were the C version. I quick search didn't give any way of "fink-ing" the fortran versions, so I gave up along the fink path. B) I'll give it another try to building kwant and see what hints that import of yours provides. I'll let you know. Again, thanks for your help as well.

Hi Pol,
as for route 1:
- what confuses me a little bit is the naming of your libraries - this seems somewhat non-standard. Can you point me to a place at the fink homepage where infos about the lapack libs is found? Or is this not the fink lapack/blas?
- Trying "import kwant.linalg.lapack" (again outside the kwant directory) can sometimes give a more specific error message, such as missing symbols etc.
Best,
Michael
