PyWafo install on Mac - Error in gumbel_r.fit2

[Bob Frat]

Has anyone tried installing PyWafo on a Mac? I am using Python 2.7.5. I downloaded source code from svn, ran build_all.py and setup.py and it seemed to go smoothly.

When I try applying the gumbel fit in the chapter 5 tutorial I get the following error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

----> 1 gum = ws.gumbel_r.fit2(Hs)
      2 tmp = ws.probplot(Hs, gum.par, dist='gumbel_r', plot=plt)

TypeError: can only concatenate tuple (not "int") to tuple

I can send the whole traceback if needed.

Thanks,
