/lib is used by the system, python related stuff should never go
there, not even look there.

Under Linux I would suggest the following defaults:

libs: /usr/local/lib, /opt/lib, /usr/lib
headers: /usr/local/include, /opt/include, /usr/include

If it matters, add also <sys.prefix>/lib, <sys.prefix>/include (some
people install Python with --prefix=$HOME, for example).

Also, compilers may use their one include/lib directories, e.g. gcc uses
<prefix>/lib/gcc-lib/i686-pc-linux-gnu/3.0.4/
<prefix>/include/g++-v3/
