CRYPT_BLOWFISH question

[Matthew Blair <me@xxxxxxxxxxxxxxxx>]

Hello all,

I've built PHP 5.2.13 on CentOS 5.4 and Ubuntu 10.04, and
CRYPT_BLOWFISH == 0 on both. I'd like to use PHPass's Bcrypt, which
relies on CRYPT_BLOWFISH being equal to 1. I've perused the source;
ext/standard/crypt.c and the configure script lead me to believe that
my systems don't support it natively.

Do you have any idea what packages are needed on either platform? I'd
rather not use PEAR's Crypt_Blowfish or Mcrypt. And yes I know 5.3.x
includes an implementation.

Thanks for your time!
