It seems to work here:

  --with-libgcrypt        Use Libgcrypt for crypto
  --with-openssl          Use OpenSSL for crypto
  --with-libz             Use Libz for compression
  --with-gnu-ld           assume the C compiler uses GNU ld default=no
  --with-libssl-prefix[=DIR]  search for libssl in DIR/include and DIR/lib
  --without-libssl-prefix     don't search for libssl in includedir and libdir
  --with-libgcrypt-prefix[=DIR]  search for libgcrypt in DIR/include and DIR/lib
  --without-libgcrypt-prefix     don't search for libgcrypt in includedir and 
libdir
  --with-libz-prefix[=DIR]  search for libz in DIR/include and DIR/lib
  --without-libz-prefix     don't search for libz in includedir and libdir

The ordering isn't perfect though, but it is still there.
