[R] Build problems on Windows with fpTeX and MiKTeX

[Erich Neuwirth]

Recently,
I upgraded MiKTeX to the latest versions, and since then there are 
problems when I try to build R and/or R packages.
I tried to build R 1.9.0 beta and R 1.8.1 patched

I am running Windows XP Pro, SP 1
MikTeX version is
This is e-TeX, Version 3.141592-2.1 (MiKTeX 2.4)
(preloaded format=latex 2004.3.27)

fpTeX version is
This is e-TeXk, Version 3.141592-2.1 (Web2c 7.5.2)
(format=latex 2004.3.23)  27 MAR 2004 21:58

With MiKTeX, it is not possible any more
do build documentation  either for R itself or for packages,
I get the following error

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

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

l.45 \newlength{\middle}


With fpTeX, I can build R itself, but when I try to build packages,
I get


(c:/Program Files/TeXLive/texmf/tex/latex/graphics/color.sty
Package: color 1999/02/16 v1.0i Standard LaTeX Color (DPC)

(c:/Program Files/TeXLive/texmf/tex/latex/texlive/color.cfg
File: color.cfg 2001/08/31 v1.1 color configuration of teTeX/TeXLive
)

! Package color Error: No driver specified.

See the color package documentation for explanation.
Type  H <return>  for immediate help.
  ...

l.123      }

You should make a default driver option in a file
color.cfg
eg: \ExecuteOptions{dvips}

)

Both versions of TeX are installed the standard way,
without changes (except adding a few local LaTeX style files).


Is this happening to anybody else?
