Comment (by Schamschula):

 There are a number of problems here:

 1) you can't have two depends_build lines, you need to continue using
 {{{\}}}

 2) py-sphinx_rtd_theme can be called from several versions of python that
 could be installed

 3) py-sphinx_rtd_theme has dependencies

 4) I'm still seeing issues with the latex documentation: there is no
 MacPorts fncychap package at the moment

 5) The revision on py-sphinx-rtd-theme needs to be reset to 0 (or the
 revision line needs to be deleted - preferred). The gsl revision needs to
 be set to 1.
