Trying to compile 1.5.63 under Debian

[Antonio PALAMA']

I have tried to compile 1.5.63 under Debian Woody without success.
./configure complains that it can't find python.h and suggests that
python-devel, or python-dev or libpython-dev should be installed.
python-dev is installed and I have Python.h sitting in
/usr/include/python2.1/      (it belongs to python2.1-dev which
was installed since it is required by python-dev).
Should I create a simlink to Python.h named python.h somewhere?

./configure also warns not to use guile ./configure --with-threads.
Is guile ./configured --without-threads available as a binary package
or should I compile it myself?

Thanks for your help,

Ciao,

Antonio
