building Mapserver on Gentoo: with-httpd

[Jeff Kowalczyk]

I'm trying to build mapserver on Gentoo linux, in preparation to attempt
an ebuild installation package for it. I have net-www/apache-2.0.52
installed.

I need information on the expectation of the with-httpd argument:

On Gentoo linux, and perhaps with httpd-2.x in general, there doesn't seem
to be an 'httpd' program etc. What is that argument looking for? With the
apr or axps options work instead (configure help says disabled)? Thanks.

Here is the (abbreviated) Gentoo file manifest for an installed
apache-2.0.52:

# qpkg -l apache | more
net-www/apache-2.0.52 *
