Cannot build OTF and TTF from Inconsolata-vf.glyphs

[spwhitton]

I am attempting to follow the instructions in README.md to produce the static OTF and TTF fonts, but I run into this error:

Based on README.md it is my understanding that the Glyphs.app scripts need be run only to produce the variable width font -- is that correct? I tried checking out the v.2.000 and v2.012 tagged releases but get the same error for those.

fontmake 2.1.4 on Debian unstable.

Thank you!

The "Building the family" section says

To build the fonts we must load sources/Inconsolata-vf.glyphs in Glyphs and do the following

Since the script is unusable without Glyphs, is Mac OS X required to build the font at all? If so, can you relax the requirement so Linux and Windows users can build too.
