Problem with running a plugin

Hey everybody,

I have installed psi4 and all tests passed. I created a new plugin, compiled and while running I get the error message:
Traceback (most recent call last):
File “/home/monika/Documents/Git/psi4/bin/psi4”, line 260, in

File “”, line 21, in

psi4.core.plugin_load(sofile)

RuntimeError:

I checked the environment:
echo $PYTHONHOME $PYTHONPATH $DYLD_LIBRARY_PATH $PSIDATADIR
empty line

which python psi4 g++ gfortran
/home/monika/psi4conda/bin/python
/home/monika/Documents/Git/psi4/bin/psi4
/home/monika/psi4conda/bin/g++
/home/monika/psi4conda/bin/gfortran

which cmake
/usr/bin/cmake

Is anyone familiar with this issue?
