Well I got it to work by commenting out the 2 lines that raised the ValueError, and everything seems to be working so far. It runs, and looks pretty; I am able to view books and was able to convert a pdf to mobi. What exactly is ImageMagick used for in calibre so I can test to see if it's working. I assumed it would be used in image converting when converting books to different formats, is that correct?
Also I did get an unrelated warning after the building.
Code:
('PoDoFo not found on your system. Various PDF related', ' functionality will not work. Use the PODOFO_INC_DIR and', ' PODOFO_LIB_DIR environment variables.')
I'm not sure what podofo is, but converting from a pdf at least works.
Edit: Nevermind about podofo, I found it.
