Hey, thanks for the instructions, but taffybar still refuses to build:

I followed your instructions exactly. Is the pxsl file actually used? I'm not sure what else to do.

Hey @cjordan, for me it worked nicely... Did you delete .stack-work in your working directory? That helped for me...

That definitely helped! I'm now struggling with some extra-deps, but I think I can work that out on my own -- thanks for the tip!

Sorry, it seems GitHub doesn't notify me for comments on gists. The pxsl file isn't used, it's just the source file for the .xslt file in a more convenient syntax. The pxsl tool converts that into the xslt xml: https://github.com/tmoertel/pxsl-tools

It just says to delete every element with a name="get_row_header_cells" or aname="get_column_header_cells" attribute - you could do that with a text editor instead if you like.
