texlive in fedora 10

[Patrick Dupre]

Hello,

my latex does not work,
  mktexfmt latex.fmt
! TeX capacity exceeded, sorry [pattern memory=262000].

I wanted to unstall siunitx which seems to require install-tl or tlmgr
which are not part of texlive2007. Are those problems related ?
I think that I should install texlive2008 but it is not available
in rpm package, what are the planes ?
The other option is to remove texlive2007 by using yum, but it is going
to remove more packages than what I want: cf. TeXmacs, lyx.

What would you suggest ?

Regards.
