Can sklearn be installed and if so in a venv?

[phansi.work]

Hello,

1 Would like to shift to DragonflyBSD from Linux for work. As a compute server.
2 Able to install really no problems at all.

Problem(s)

1 I use python, with sklearn. In a virtual environment, not global as require different versions.
2 Without pasting the (huge error) pip install sklearn APPEARS to fail because be lack of a fortran compiler.
3 sklearn seems to need one, cannot locate it, 
4 gcc claims to have a fortran compiler, NOT gfortran but with flags which I am unable to decipher.

cheers
