[Rd] R package installation (PR#13726)

[Prof Brian Ripley]

This is a problem in your specification to R of the peculiarities of 
your system, not in R itself.  You have only specified some of the 
settings you need, and in particular as you are using Fortran 90 code 
and a shared R library you need more than a typical user would.

Not current.

Copied I suppose from the R-admin manual (without credit)?  The 
current version suggests

CC="gcc -m32"
F77="gfortran -m32"
FC=$(F77)
CXX="gcc -m32"
OBJC=$(CC)
LIBnn=lib

which I suspect you will find more successful.  However, you seem not 
to have studied the file config.site, which lists many settings you 
may need to specify.  Reading there, it seems that either 
SHLIB_FCLD="gfortran -m32" or SHLIB_FCLDFLAGS="-shared -m32" would be 
appropriate.

Hmm, has Fortran 90 files inside: these do not use the same settings 
as 'Fortran'.
