Compile errors with Apache2 + mod_ntlm_winbind

[Scott Barnett]

I'm having compile problems with mod_ntlm_winbind when I'm using
Apache 2. I've reproduced the exact problem on Ubuntu and Redhat
Enterprise so hopefully this will help rule out distro specific
problems, ie. I get it when compiling apache from source. I can't use
rpm or deb versions (I've been colouring outside the square a bit too
much).

The compile process basically does not produce an .so file and then
complains that it can't copy it to the modules/ folder. I can get it
to compile if I _don't_ map the binaries to the correct places with
the apache configure script, but only by calling apxs directly ("make
install" doesn't work).

Example 1:
- A fresh apache install with options:
--enable-so
--bindir=/usr/bin
--sbindir=/usr/sbin
--sysconfdir=/etc/httpd
Apached installed ok

- Generic mod_ntlm_winbind install:
autoconf/configure/make/install
Fails:

***********************************************************************************

Example 2:
- A fresh apache install with no configure options except the module loader:
--enable-so
Apache installed OK

- Generic mod_ntlm_winbind install:
autoconf/configure/make/install
Failed

- Tried using a configure option:
[root at web02 mod_ntlm_winbind]# ./configure
--with-httpd=/usr/local/apache2/bin/httpd
<snip>
checking for httpd... /usr/sbin/httpd
./configure: line 2747: /usr/sbin/httpd: No such file or directory
<snip>
"httpd" was installed in /usr/local/apache2/bin/httpd because that's
the default location unless you specifically map it, this should be ok
to overide with the configure option which doesn't look like it's
working.

- Tried install with just apxs
/usr/local/apache2/bin/apxs -DAPACHE2 -c -i mod_ntlm_winbind.c
Installed mod_ntlm_winbind.so, .c, .a, and .la in modules/
