I wanted to add Python 2.7 to Unix.
I downloaded the sources to the VirtualBox on which the Unix is installed and run

./configure --prefix=/usr       \
            --enable-shared     \
            --with-system-expat \

without problems.

However, when I try to run make, it fails on:

cc –Kpthread –Wl,-Bexport –o python Modules/python.o libpython2.7.a -lsocket –lnsl –lpthread –ldl –lm 

Undefined                       first referenced

_PyInt_FromDev                      libpython2.7.a(posixmodule.o)     
UX:ld: ERROR: Symbol referencing errors. No output written to python
