Update python to 2.6
glibc's version: glibc-2.5-81

*problem
do_compile cracklib failed
...
| ../lib/.libs/libcrack.so: undefined reference to `be64toh'
| ../lib/.libs/libcrack.so: undefined reference to `htobe16'
| ../lib/.libs/libcrack.so: undefined reference to `htobe32'
| ../lib/.libs/libcrack.so: undefined reference to `htobe64'
| ../lib/.libs/libcrack.so: undefined reference to `be32toh'
| ../lib/.libs/libcrack.so: undefined reference to `be16toh'
| collect2: ld returned 1 exit status
...

*analysis
cracklib invokes C functions `be16toh/be32toh/be64toh/htobe16/htobe32/htobe64'
to fix endian issue on multi platform, but these functions are nonstandard
which were added to glibc in version 2.9. So do_compile failed while host's
glibc version < 2.9

*solution
Use standard `htons/htonl/ntohs/ntohl' instead. For the `be64toh/htobe64',
there is not similar functions, we define `ntohll/htonll' on local to replace.

There are two solution to fix this issue, and Mark Hatle's is better.

Merged into master:
