Also, /usr/local/texlive/texmf-local is for system-wide local additions, not individual user local additions, which are normally placed in TEXMFHOME (on Linux systems, standardly /home/<user>/texmf; on a Mac /Users/Library/texmf). If you have a single user system, there's not much advantage to installing local packages in /usr/local/texlive/texmf-local, I think. – Alan Munn Sep 9 '11 at 21:33
