Then I installed TeXworks, but it won't work correctly. When I try to compile a .tex, the console spits:
! LaTeX Error: File `paralist.sty' not found.
Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)
Enter file name:
But paralist.sty actually exists already, at /usr/local/texlive/2012/texmf-dist/tex/latex/paralist/paralist.sty
So I enter this file name, but then TeXworks asks for the next one, and another one, and so one. All files that exist. Once all are entered, the document is compiled just fine.
That wouldn't be that bad if TeXworks was remembering the files' locations once I pointed it at them, but it doesn't. Next time I'm trying to compile, it asks for the same files again.
So my question basically is: what went wrong during the installation? how can I avoid these error messages?
