[gentoo-user] /usr/lib/libgdbm_compat.so.3: undefined symbol: __guard

[Grant <emailgrant@gmail.com>]

I get this when emerging python on a system I'm bringing up to date
after 3 years of non-use:

*** WARNING: renaming "dbm" since importing it failed:
/usr/lib/libgdbm_compat.so.3: undefined symbol: __guard

The compile eventually fails with:

Failed to find the necessary bits to build these modules:
_bsddb             _tkinter           bsddb185
sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for
the module's name.

This is python-2.6 but I get the same from 2.7 and 3.1.  I was able to
emerge python-2.6 earlier in the updating process so I'm not sure why
it's failing now.  I'm halfway through an emerge -e world to see if
that helps.  The system is up-to-date now and working fine although I
still need to update the kernel, gcc won't compile above 4.3.4, and
udev gets crazy above 141.  I'm on this profile:

hardened/linux/x86

Any ideas?
