[Rd] Rcmd SHLIB error

[Gabor Grothendieck]

I am getting this error message when I try to run Rcmd SHLIB myprog.c.
 There appears to be a missing / between etc and i386 in the path.  I
am on Windows Vista and am using R version 2.12.1 Patched (2010-12-16
r53864) and just downloaded Rtools 2.12 today.   Is this a bug in R?
How can I resolve this?

C:\tmp2>Rcmd SHLIB myprog.c
