bitbake php fail

Using angstrom2008.1 disto. I try to create a xxx-image.bb for my project.

But bitbake stuck at PHP do_config:

  checking for crypt in -lcrypt... (cached) yes
  checking for pkg-config...
/home/jason/angstrom2008/build/tmp-angstrom_2008_1/sysroots/i686-linux/usr/b
in/pkg-config
  checking for OpenSSL version... >= 0.9.6
  checking for CRYPTO_free in -lcrypto... no
  configure: error: libcrypto not found!
  ERROR: Function do_configure failed

Libcrypto should inside openssl right? Any suggestion?
