libpython exports not available to python plugins

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile current version (1.1.91) on linux against IDA Pro 5.4
2. Install MySQLdb python extension (although other extensions also suffer)
3. Open python script box (Alt-8), execute 'import _mysql'

What is the expected output? What do you see instead?

Expected output is nothing, Actual output is an ImportError exception
because _mysql.so depends on Py_* symbols in libpython[X.Y].so but these
are not exported due to the way IDA Pro loads python.plx, and implicitly
loads libpython[X.Y].so

What version of the product are you using? On what operating system?

See above.

Please provide any additional information below.

A patch is available which solves this issue for me. It works by calling
dlopen() explicitly on libpython[X.Y].so and updating the flags to export
symbols from the library.

I do not know if a similar issue exists on MacOS X, and I am unable to test
this presently.

Patch to python.cpp which fixes this issue for me.
