Working within the Hub framework this is straightforward. If you are using
public releases rather than special builds of the tools then it should be quite
easy.
Supposing you needed to test with Haskell Platform 2011.2.0.1 and hexpat-0.19.7:
# install the platform (probably done already)
sudo yum install haskell-platform-2011.2.0.1-hub
# create new hub 'test-2011.2.0.1' based this HP
hub init 2011.2.0.1 test-2011.2.0.1
# install hexpat-0.19.7 into it
hub install-into test-2011.2.0.1 hexpat-2011.2.0.1
Repeat as necessary to create your array of test environments.
Now you just have to arrange select the appropriate hub for each test. Suppose
the environment variable $testhubs contains all of your test hubs
('test-2011.2.0.1', etc.), then the following shell command would prime the
tools to successively use each of the test environments on each invocation of
make.
for h in $testhubs; do HUB=$h make; done
Note that the justhub distribution isn't necessary for this -- you can do it
manually.
But it does make it easier.
