It definitely should be part of the default Python install. On my
Debian system:

=====
$ python
Python 2.3.5 (#2, Sep 4 2005, 22:01:42)
[GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2
Type "help", "copyright" , "credits" or "license" for more information.[color=blue][color=green][color=darkred]
>>> import math
>>> repr(math)[/color][/color][/color]
"<module 'math' from '/usr/lib/python2.3/lib-dynload/math.so'>"[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

$ dpkg -S /usr/lib/python2.3/lib-dynload/math.so
python2.3: /usr/lib/python2.3/lib-dynload/math.so
=====

Perhaps you should use the official Python package for your operating
system, or double-check you built and installed the source packages
the way you want them.

Just as you have on your system and it's there.
So why in the heck isn't it loading with:
import math ????

This is strange.

That doesn't look like a python program, File "<string>" means it's an
embedded script. When a script is embedded it is responsibility of the
caller (blender application) to setup correct path to modules.

Try to insert
==============
import sys
print sys.path, sys.version, sys.executable
==============
right before the failing "import math". The next step is most likely to
RTFM how to properly setup python embedded into blender. If everything
looks as described in the manual, it's a bug in blender.

Is the Python that you are running actually 2.3? Some Linux systems have
both Python 1 and a Python 2 installed. Typing "python" at a command line
often gets Python 1, because the vendor's configuration scripts assume
that.

However, that doesn't answer the question, because even Python 1.5 should
have a module called "math".

Maybe he's running a UK-based distro which has
renamed the math module to maths? (I have to work
really hard to remember *not* to put the "s" on the
end when I import it!
