[O] Test problems again

[Neuwirth Erich]

I need help to locate a configuration problem.
As I alreay wrote I am building org-mode on 2 Macs.
On the desktop, I do not have any problems, and all the test pass (except the 
ones where 
the testing routines tells they are expecting to fail).

But on the MacBook (which essentially has the same configuration)
testing fails:

Code block evaluation complete.
htmlize.el 1.34 or later is needed for source code formatting
Exporting...
HTML export done, pushed to kill ring and clipboard
  passed   33/137  test-ob-lob/export-lob-lines
13 src blocks added to Library of Babel
  passed   34/137  test-ob-lob/ingest
Babel evaluation exited with code 1
  passed   35/137  test-ob-sh/dont-error-on-empty-results
  passed   36/137  test-ob-sh/dont-insert-spaces-on-expanded-bodies


Here the process hand and I need to kill it with C-C

^Cmake[1]: *** [test-dirty] Error 2
make: *** [up1] Interrupt: 2

Meanwhile I am also able to use testing/README to start interactive testing.
If I am not asking too much, it would help if somebody briefly explains to me
how I could dig into more details at the place where things go wrong.
I do not understand why I get passed ... with consecutive numbering, but 
between these messages I get the
exited with code 1 message.

Can anybody enlighten me?
