My real problem is that I am trying to use a package which depends on
siunitx, and it complains on compiling with the following error:
(/usr/share/texmf/tex/latex/siunitx/siunitx.sty ! Package siunitx Error: Support package expl3 too old.. See the siunitx package documentation for explanation. Type H <return> for immediate help. ... l.29 } )
I would really rather install the package using a package manager. I'm on Gentoo, which has a nice little tool called g-ctan that creates distro packages from packages on CTAN.
expl3 isn't in the package database, even though it can be found on CTAN.
It says that it is a wrapper for experimental LaTeX 3... the package name is
l3kernel. Eek! Experimental!
Is it safe for me to install
l3kernel? Is it going to break my LaTeX installation?
