Installation problem on Unix

[Anon]

Hi,

Please help.

I am trying to install php4.1.1 on a unix server which has apache installed. I am able to run this command:
./configure --with-mysql --with-apxs=/opt/apache/bin/apxs

However, when come to 'make', i will get the following warning:
*** Warning: This library needs some functionality provided by -lcrypt.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have.

What should I do to solve this? I have include the path for /usr/bin/ where the crypt resides.

Thanks.
