SOLVED: [R] Rcmd SHLIB in rw1031 (R for Win)

[Agustin Lobo]

I had one missing directory in my path.
mingw-1-1-tar.gz contains 2 "bin" directories.
I used tar zxvf MinGW-1.1.tar.gz from directory rw1031/Rwint
and got a rw1031/Rwint/bin directory (which I did include in
my path), but also another rw1031/Rwint/mingw32/bin (which
I had not seen). 

I also have included E:\rw1031 and E:\rw1031\bin in my path,
but it seems to me that the missing rw1031/Rwint/mingw32/bin 
was the cause of the problem.

Thanks!
