Probably a packaging bug.

The Debian/Ubuntu packages are horribly out of date.  Our latest stable
release is also quite old now.  Try one of the 'release of the day'
tarballs and follow the instructions.

Additionally to the instructions I recommend the following configure
line, for say the RODT 2008-07-07

./configure --prefix=/usr/local/mercury-rotd-2008-07-07 \
  --enable-libgrades=asm_fast.gc

then create a symlink from /usr/local/mercury to the new installed
complier, this will make changing versions easy.

In my limited spare time I'm working on new packages for Debian.
This may be some time away since I have very little spare time.

Hope this helps.
