Dear All

First off, let me just add my thanks to all the people involved in the
production of R-1.0.0... Well Done!!

I'm getting an error installing R-1.0.0 on RedHat 5.2, perl 5.004_04.  It
did not occur under Solaris 2.6 with perl 5.004_01.

During install of the base package (and akima, bootstrap, etc) it gets to the
point of building the help pages and it gives this error:  

>>> Building/Updating help pages for package `base'      Formats:
text html latex example   HairEyeColor                              html   
latex   example   Hershey                           text    html    latex  
example   Hyperbolic                        text    html    latex   example
  Hypergeometric                    text    html    latex   example
  IQR                               text    html    latex   example
Substitution loop at /a/euler/export/local/linux/pkg/R-1.0.0/etc/Rdconvlib.pl line 1262, <rdfile> chunk 3268.   

and the install of that package stops, half way through the generation of the
help file for InsectSprays (which comes next after IQR).

Line 1262 of etc/Rdconvlib.pl is:
        $ntext =~ s/^[\n]*//go;

and "man perldiag" says:
  Substitution loop
           (P) The substitution was looping infinitely.
           (Obviously, a substitution shouldn't iterate more
           times than there are characters of input, which is
           what happened.)  See the discussion of substitution in
           the section on Quote and Quote-like Operators in the
           perlop manpage. 

The last few lines of the aborted help/InsectSprays is:

     The counts of insects in agricultural experimental units treated
     with different insecticides.

------ stops here (but of course it shouldn't) ---------

Any suggestions ?
