If you have the old environment already there, then it should be as 
simple as:

mkdir work
cd work

# if you already have a fork it might be better to work with that
git clone git://github.com/pgRouting/pgrouting.git

cd pgrouting
git checkout sew-devel-2_0
tools/doit
(cd build && sudo make install)

tools/test-runner.pl


tools/doit - a simple shell script to configure and compile. It creates 
a directory "build" and all the build atrifacts go into it.

tools/test-runner.pl - is a perl script the runs the automated tests in 
the database. If you have pg 9.1+ it assumes you can use "create 
extension " for both postgis and pgrouting. If you have pg <9.1 then it 
assumes you have already create a template_pgrouting database that has 
postgis installed in it.

Currently, I have db_* test disabled as they crash. you can run them 
manually with:

create a database with postgis and pgrouting installed in it say "test1"

# load the test data for dijkstra
psql -U postgres -h localhost -f 
src/bd_dijkstra/test/bd_dijkstra-any-00.data test1

# run a test(s) for dijkstra (test are 01-06)
psql -U postgres -h localhost -f 
src/bd_dijkstra/test/bd_dijkstra-any-01.test test1

# load the test data for astar
psql -U postgres -h localhost -f src/bd_astar/test/bd_astar-any-00.data 
test1

# run a test(s) for astar(test are 01-06)
psql -U postgres -h localhost -f src/bd_astar/test/bd_astar-any-01.test 
test1

I have run both your unit test files in "tester" directory and they run 
ok, So it has something to do with the integration.

Thanks,
   -Steve
