Does this happen with the code from the master branch here? (TILP and the tilibs should always be installed/updated from this repo, not packages etc)

[jojomoore2007]

No, it does not. I could not get either the code from http://lpg.ticalc.org/prj_tilp/linux.html or this repo to install, so I installed the APT package. I will continue trying to install, but if this proves to be unsuccessful, I will submit an issue in regards to that as well.
