Yes, that is a bug. Surprisingly enough this bug has existed for years 
now without being detected. Although these days there isn't a profit in 
gzipping a celfile (you don't gain anything by gzipping a binary file), 
so maybe that explains it.

Anyway, fixed in the devel version (1.31.6). This should propagate 
through the build system and be available in 24 hours or so. Note that 
you will need to use the devel version of R in order to get it via
