Comment (by glynn):

 Replying to [comment:2 marisn]:

 > Still the issue is valid - configure step should check build time
 dependencies and fail if they are not met. It is done for C, C++ - why
 Python should be different?

 For C/C++, the checks are often part of a more significant process, i.e.
 ensuring that the necessary parameters are stored in Platform.make,
 config.h, etc. That has to be done in order for the build to work, even
 when everything is in order. The fact that you get an error if something
 is wrong is almost a side-effect.

 At present, we don't even check whether Python is installed. For C, the
 relevant compiler checks are part of autoconf (AC_PROG_CC); there isn't an
 equivalent for Python. With Python 3 becoming more common, it may be
 worthwhile checking for Python 2.x specifically.
