I need to install Python 2.7 in two architectures, but under one file system. I thus configure:

/home/cellnet/michaelk/SRC/Python-2.7.3> ./configure --prefix=/home/cellnet/michaelk/biocluster --exec-prefix=/home/cellnet/michaelk/biocluster -q

When I compile and then run "make install", it will try to copy libraries to "/home/cellnet/michaelk/lib64/python", i.e. it will try to copy files outside the specified prefixes. The step is "make sharedinstall", which fails because I've temporarily made the lib64 directory read-only: 

[michaelk@biocluster2] /home/cellnet/michaelk/SRC/Python-2.7.3> make sharedinstall

Python build finished, but the necessary bits to build these modules were not found:
bsddb185           dl                 gdbm            
imageop            sunaudiodev                        
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
