I am using Windows 2000. I have followed the advice on rebasing the 
system, to no avail

The steps I've followed are:

	- Re-download the mod_php4 package (download only, not install).

	- Run rebaseall from the prompt. It runs w/o any error messages that I 
can see, and then...

cohen AT lazarus /usr/lib/apache
$ rebaseall

cohen AT lazarus /usr/lib/apache
$ /usr/sbin/apachectl start
Syntax error on line 238 of /etc/apache/httpd.conf:
Cannot load /usr/lib/apache/libphp4.dll into server: dlopen: Win32 error 193
/usr/sbin/apachectl start: httpd could not be started

Let's hope it's solved soon ;)
 From what I've seen in the answers to my question, we should be seeing 
some changes to the apache + php problem soon (as the maintainer has 
said something on that lines ;)

This problem seems to have gone away after rebasing (rebaseall). At 
least, now I can get httpd to start with the
LoadModule ssl_module         lib/apache/libssl.dll
and
AddModule mod_ssl.c
lines in httpd.conf.

Now I "only" have to read the mod_ssl docs and see what I need to get a 
https server set up and running ;)

Done that, but it seems the problem has not gone away.

Been doing some more digging. I was wondering if the "bad" .dll was 
libphp4.dll or one of its depenedencies.
The cygcheck output is:

Use -h to see help about each section

And using MS's Dependency walker on libphp4.dll (after adding 
c:\cygwin\bin to the lib search path) it says: (see attached file, 
depwalk.txt)
