rebaseall does the following to get a list of objects that need to be=20
rebased:

     find /etc/setup -name '*.lst.gz' | \
         xargs gzip -d -c | \
         grep -E "\.(dll|so)\$" | \
         sed -e '/cygwin1\.dll$/d' -e '/cyglsa.*\.dll$/d' -e 's/^/\//'

The gems, I guess, do not add lst.gz files to the /ets/setup, thus=20
rebaseall does not know about any DLLs or SOs they install.
But it is possible to provide a list of objects that need to be rebased=20
in addition to the default list when you run rebaseall.

You can probably do something like this:

     find /lib/ruby/gems -iname '*.so' > /tmp/ruby.gems.local.so.lst

Then "quit" cygwin and rebaseall like this:

     /usr/bin/rebaseall -T /tmp/ruby.gems.local.so.lst
