What distro are you using? I don't have any package with 'numpy' in
it's name, available.

Allright, so I have these installed too, just where I would expect them
to be according to my --prefix=/usr/local:

This I would never guess. I thought they would be installed just as in
case of the old --with-python. And since they were not installed, I
assumed they were not built. But look, they are all there in my source
GDAL directory:

Summarising:

1. I don't need any "numpy-dev" package; apparently python2.4-numeric
or python2.4-numarray provide all the headers needed (dont't know which
one exactly).

2. The warning in config.log: "checking for NumPy include files...
missing" is bogus and does not affect building --with-ngpython at all.
However confusing it is.

3. I don't understand why the python scripts from /pymod directory are
not installed when using --with-ngpython, while they are installed when
I build with the old-fashioned --with-python. Confusing as well.

Thanks for helping me. Now I can get back to playing with VRT and
gdal_merge.py.

Best,
Maciek
