[R-SIG-Mac]trouble using R CMD

[David Firth]

-- 
I have recently begun using R 1.3.1 in Darwin/X11.  The Darwin I have 
is that which came with Mac OS 10.0.4.

My first experience with trying to use R CMD has not been a success. 
I am trying to index a package from its documentation, in the 
standard way:

[Localhost:lib/R/bin] david% echo $R_HOME
/usr/local/lib/R
[localhost:lib/R/bin] david% echo $PATH
/sw/bin:/sw/sbin:/Users/david/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/X11R6/bin
[localhost:lib/R/bin] david% echo $PERL5LIB
/sw/lib/perl5
[localhost:lib/R/bin] david% echo $PERLLIB
PERLLIB: Undefined variable.
[localhost:lib/R/bin] david% which R
/usr/local/bin/R
[localhost:lib/R/bin] david% which perl
/usr/bin/perl
[localhost:lib/R/bin] david% R CMD Rdindex ~/relimp/man/*.Rd > INDEX
/usr/local/lib/R/bin/Rcmd: command not found: Rdindex [37]
[localhost:lib/R/bin] david% pwd
/usr/local/lib/R/bin
[localhost:lib/R/bin] david% ls
BATCH      LINK       Rcmd       Rdconv     SHLIB      help
COMPILE    R          Rcmd~      Rdiff      Sd2Rd      libR.dylib
INDEX      R.bin      Rd2dvi     Rdindex    build      libtool
INSTALL    REMOVE     Rd2txt     Rprof      check      pager

R CMD appears to be unable to find "Rdindex".  Can anyone suggest 
what might be wrong?

I have various other packages installed using fink (and the fact that 
PERL5LIB is set to /sw/lib/perl5 is a symptom of that).  Could that 
be the cause?

Thanks,
David
