[Rd] Cross-compile errors under R-2.4.0 and R-2.4.1

[Prof Brian Ripley]

The 2.4.0 issue has been well documented only last week, in the thread

https://stat.ethz.ch/pipermail/r-help/2007-January/123303.html

as well as in an answer I had already posted.

I am almost certain the issue for 2.4.1 is user error.  Remember you need 
to set in MkRules

## =================== cross-compilation settings  =================

...

# path (possibly full path) to same version of R on the host system
# R_EXE=R

R 2.4.1 does have seq_along, so it must not be the same version.
