I tried to follow the instructions in $TADM_DIR/docs/install.txt, but was unable to get the results specified in the install.txt file.
On one machine I got values below in both cases (tennis and parse_selection), on another machine I got the same result on the tennis example, but not on the parse_selection. On the machine both were different, there were errors installing petsc, as specified by make test below:

on the other machine, I saw no such errors from petsc, and only saw the problem when the result from the parse_selection exercise was different. What would be my way to find out why I get a different result? What versions of gcc, g++ and g77 and f77 and python are recommended / necessary?
Thanks.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
PETSC used to be very problematic for installation, but the most recent version went very smoothly for me on Ubuntu linux (Dapper Drake). I'm using the following versions:
g77: GNU Fortran (GCC) 3.4.6 (Ubuntu 3.4.6-1ubuntu2)
gcc/g++ (GCC) 4.0.3 (Ubuntu 4.0.3-1ubuntu5)
Python 2.4.3 (#2, Oct 6 2006, 07:52:30)
If the PETSC install doesn't go right, it's unlikely that TADM will work correctly. Not using MPI can make the PETSC install work more smoothly.
