buildem broke gdb on fedora

[tingzhao]

gdb returns the following error

gdb: symbol lookup error: gdb: undefined symbol: PyUnicodeUCS4_FromEncodedObject

after buildem/lib added to the LD_LIBRARY_PATH. The problem might be related to incompatible python build in buildem.

The problem might be related to incompatible python build in buildem.

Right. The issue is that gdb is linked against your system's version of libpython.so, but you have activated buildem's version python, which isn't identical.

Here's how to fix it:

Since this is likely to come up again, I've just added a note about this issue to the BuildEM readme.
