Trying the hello-world-example yields the following, while other examples seem to work just fine:
The 'ffi_prep_cif' libffi call failed for function "TTF_RenderUTF8_Blended".

It seems I'm generally able to use Sketch, but any attempts at text cause the same error to appear.. I didn't know Sketch was supposed to show that nice red screen with errors because that has failed before with the above error.. :D

I had to symlink my libffi to whatever is the latest version. For example:
/usr/lib/x86_64-linux-gnu/libffi.so -> libffi.so.7.1.0

This seems to be a dupe of #38, so closing!
