           Summary: Unit tests incorrectly assume that Biopthyon was built
                    from source
           Product: Biopython
           Version: Not Applicable
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P4
         Component: Unit Tests
        AssignedTo: biopython-dev at biopython.org
        ReportedBy: bsouthey at gmail.com


If Biopython is not built from source and the tests are run from a different
place than the installation, the test that use C objects fail because these are
not found (an example is below).

Currently the test environment uses the Biopython in the build directory. It
would be nice to be able to optionally specify some other Biopython such as the
installed version using say a command line argument.

Example of a failure:
