You can plot the growth in popularity of different Ubuntu packages here:
http://people.debian.org/~igloo/popcon-graphs/index.php
For example, the popularity of clisp and sbcl have risen sharply over the
past two years but cmucl has not and gcl even declined in 2005:

The total number of installed Lisp compilers on Ubuntu systems running the
popularity contest package seems to be around 1,600.

if we would like to interpret this numbers not for comparison between
different lisp implementations (or similar packages), it's pretty hard to do
this because:
absolute number increases as more people are getting Ubuntu
relative number decreases as more non-programmers are getting Ubuntu
so we need to normalize by a count of programmers using ubuntu, if we'd like
to see non-biased time sequence.
unfortunately there's no such button there.. i'd say being a programmer
highly correlates with using one of version system.
we see popularity of CVS decreased from 80% to 30% -- i think both
programmer percentage decreased and CVS is actually outdated.
SVN has more complex line of popularity with peak of 40%, now it seems to be
about 25%.
probably we can conclude that number of programmers among Ubuntu users
decreased aprox 2.5 times.
SBCL's popularity in percents decreased from 2.4% to 1%, so it looks like
SBCL popularity among programmers didn't change much.

Slight cockup on my part: the page I cited is Debian's results. I can't find
an equivalent for Ubuntu.

If you want market share rather than absolute number of users, yes. I think
the number of users is quite interesting.
According to the current stats for Ubuntu:
http://popcon.ubuntu.com/
clisp: 1183
sbcl: 853
gcl: 326
cmucl: 322
I was quite surprised to see that clisp is so popular. I thought everyone
was using SBCL...
