In Make.mpl there are the lines:

readlib(latex):
unassign('`latex/exp`'):
unassign('`latex/ln`'):
unassign('`latex/log`'):

Then in LaTeX.mpl they are redefined.

This probably explains what's happened. The original way that Maple
defined packages was via tables, hence the syntax linalg[det], but
then Maple introduced modules (probably in Maple 6) and new packages
that were developed after that time were written as modules rather
than tables; a module function may use the (preferred) syntax 
linalg:-det (or for compatibility, the table syntax).

I'm guessing then that latex has been rewritten as a module, and
so the re-definitions of `latex/exp`, `latex/ln` and `latex/log` 
need to be re-written in module syntax to work in Maple 9.

As an interim measure, `just to get things working', I would comment
out the lines

unassign('`latex/exp`'):
unassign('`latex/ln`'):
unassign('`latex/log`'):

in Make.mpl and then also comment out the redefinitions of 
`latex/exp`, `latex/ln` and `latex/log` in LaTeX.mpl.

Probably, you will need to comment out all the other `latex/...`
command definitions too in LaTeX.mpl, which would leave just 
`LaTeX/trim` and `LaTeX`.

Could you check to see whether the documentation (or possibly the
manuals that come with Maple 9) make any mention of a rewriting of
latex as a module? Without reading in Console.mpl what output do you
get with:
