TexLive is a very decent Latex implementation, however if you want to write DIN conformable letters using g-brief you might get an error message like that:

! LaTeX Error: Command \Telefon already defined.
Or name \end... illegal, see p.192 of the manual.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H   for immediate help.
 ...

l.48 \newcommand\Telefon{\mvchr{84}}

This bug is in g-brief with newer versions of marvosym.sty. So all you have to do is edit line 48 of /texlive/texmf-dist/tex/marvosym.sty and uncomment it.
This bug might affect all unices, not only Solaris.
