After upgrading to the latest version of gpkit I get the following error when using mosek as the solver, running the simple test case from the documentation:

">> python gptest.py
Traceback (most recent call last):
File "gptest.py", line 16, in
sol = m.solve(verbosity=0, solver = 'mosek')
File "/Users/chriscourtin/dev/gpkit/gpkit/constraints/prog_factories.py", line 124, in solvefn
result = progsolve(solver, verbosity, **kwargs)
File "/Users/chriscourtin/dev/gpkit/gpkit/constraints/gp.py", line 148, in solve
solverfn, solvername = _get_solver(solver, kwargs)
File "/Users/chriscourtin/dev/gpkit/gpkit/constraints/gp.py", line 39, in _get_solver
from .._mosek import expopt
File "/Users/chriscourtin/dev/gpkit/gpkit/_mosek/expopt.py", line 96, in
MSK = ModuleShortener("MSK", load_library(settings["mosek_lib_path"]),
KeyError: u'mosek_lib_path'
"

As far as I can tell the mosek installation is still working; python is able to load the solver outside of gpkit, and the license file is active.
