I use BasicTeX on OS X 10.9 Mavericks (for space problems on a Macbook Air). I usually manage to find the packages that I miss by interpreting pdflatex-errors, but this time I cannot find a clue to what package I miss.
I tried using
\usepackage{newtxmath}
but I get the following error message:
! I can't find file `zxxrl7z'.
Of course the package newtx is installed. Could someone tell me which package zxxrl7z belongs to?
boondoxwas exactly the package I needed! Thanks! You can write an answer and I will flag it. Can I also ask you how you found the package based on the file name, so that I can use the same method in the future? Did you locate it in your distribution? – Pincopallino Apr 29 '14 at 14:46
