Oh, but they DO. Try to do parallel installations.
Being able to run Fricas and Axiom in parallel would be great.

I try hard to add the critical patches from OpenAxiom and Fricas
and I run into this all the time. I'd estimate that reverse-engineering
critical patches takes about 25% of my time. Patches rarely have
test cases that illustrate what was broken or fixed so I have to 

I've tried to minimize this pain "outward" by documenting how to 
install the new )help facility and how to install the regression 
test facility. When the new )browse facility gets more stable I'll
also document how to port it to the other systems. In addition my
patches give rather-longer explanations of what they do so it is
easier to understand if they might be of interest.

Unfortunately the )help, )browse, regression testing, and the coming
)example facilities all are closely related to literate programming
which will make them hard to port to other systems.

Sigh. See the mailing list archives.
