[XML-SIG] Problem installing Pyxml

[Natassa Gioti]

Hallo,
 I have Python 2.5 version on a MacOSX, and tried to install Pyxml:
python setup.py build

error: command 'gcc' failed with exit status 1

I previously had problems with other programs I tried to install, as if no
gcc compiler could be found, but do not know how to check that indeed ( I
used alternative programs previously).
Could you please help me with that? I am a newbie in such issues...
Thank you in advance,
