I wish to use the Helvetica package. I installed the
psnfss package with tlmgr (and in a fit of desperation other font-related packages, such as
ae). However, I still do not have any
phvr7t files in my texlive distribution. I do have
/texmf-dist/fonts/tfm/metapost/, if that helps.
I used the Mactex texlive-2012-basic installer.
EDIT: I manually installed
psnfss, because tlmgr did not copy any font files into the texmf distro. I now have
/texmf/fonts, but Latex can't seem to find them.
