>Description:
This is really a lang/python24 problem, but I see it from py-Orbit, as part of 
installing meta-pkgs/gnome.  net/py-ORBit fails to configure with:

checking for headers required to compile python extensions... found
checking for python libraries... not found
configure: error: could not find Python headers
*** Error code 1


From config.log:

configure:20120: gcc -pthread -o conftest -O2 -I/usr/pkgroot1/include 
-I/usr/pkgroot1/include/python2.4 -I/usr/include -I/usr/pkgroot1/include 
-I/usr/pkgroot1/include/python2.4 -I/usr/include 
-I/usr/pkgroot1/include/python2.4 -L/usr/pkgroot1/lib -Wl,-R/usr/pkgroot1/lib

-L/usr/lib -Wl,-R/usr/lib conftest.c  -L/usr/pkgroot1/lib -lm -lpthread -ldl 
-ldb4 -lutil -lpython2.4  -pthread -lpthread -lrt >&5
/usr/bin/ld: cannot find -ldb4
collect2: ld returned 1 exit status
configure:20126: $? = 1

>How-To-Repeat:
Build net/py-ORBit (or probably any other Python strap-on) where the Python 
libraries link with libdb4.so that isn't natively available.
>Fix:
This patch is a workaround, but it isn't correct.  The correct fix needs to 
determine whether Python used bdb.buildlink3.mk at build time before doing 
something like this.

OR, maybe the -ldb4 shouldn't be here:

fgrep -- -ldb4 /usr/pkg/lib/python2.4/config/Makefile 
LIBS=           -lpthread -ldl -ldb4 -lutil

That seems to be what is causing the link time error in py-Orbit, but it isn't 
really necessary:

ldd /usr/pkg/lib/libpython2.4.so|fgrep db4
        libdb4-4.6.so.6 => /usr/pkgroot1/lib/libdb4-4.6.so.6 (0xb7d4c000)
