You have to install it outside the area tlmgr manages. The possibly
best option (I did not read the other suggestions) is to install in /
usr/local/texlive/texmf-local. You need "elevated privileges", and
again to switch it off and on. And therefore, for this ability and
simplicity, I recommend system-wide.
How does the switch work?
By presenting TeX the proper /usr/local/texlive/texmf-local/ls-R file.
How to build the switch?
After installation of the package *and* before you run "sudo texhash /
usr/local/texlive/texmf-local" you need to save the old /usr/local/
texlive/texmf-local/ls-R file: "sudo mv /usr/local/texlive/texmf-local/
ls-R /usr/local/texlive/texmf-local/ls-R-off". Now run texhash/mktexlsr.
How to switch on/off?
After you've run texhash the unstable package is "on": TeX will find
its components in the ls-R file. To switch it off execute this: "sudo
mv /usr/local/texlive/texmf-local/ls-R /usr/local/texlive/texmf-local/
ls-R-on ; sudo mv /usr/local/texlive/texmf-local/ls-R-off /usr/local/
texlive/texmf-local/ls-R", to switch it on: "sudo mv /usr/local/
texlive/texmf-local/ls-R /usr/local/texlive/texmf-local/ls-R-off ;
sudo mv /usr/local/texlive/texmf-local/ls-R-on /usr/local/texlive/
Will it work?
Not always, I presume... The problem comes from tlmgr: after
installation of some software it will run texhash/mktexlsr. Without

-rw-r--r-- 1 root wheel 1679 17. Feb 18:45 /usr/local/texlive/2010/
-rw-r--r-- 1 root wheel 27933 17. Feb 18:44 /usr/local/texlive/2010/
So the file /usr/local/texlive/texmf-local/ls-R will be overwritten
with the on-contents. To prevent this from happening you can build the
switch this way:
Save the off state as before and after "sudo texhash /usr/local/
texlive/texmf-local" was run save the ls-R file (on state) as: "sudo
cp /usr/local/texlive/texmf-local/ls-R /usr/local/texlive/texmf-local/
ls-R-on". To operate the switch don't mv (rename) the files but copy
the appropriate one:
To switch on: sudo cp /usr/local/texlive/texmf-local/ls-R-on /usr/
To switch off: sudo cp /usr/local/texlive/texmf-local/ls-R-off /usr/
So tlmgr will update only a copy and no original. Before using the
original PGFplot you should actively switch off the unstable
