Hello,

I'm new to the list... mostly for this problem actually. I'm a PHP developer
at my company, and we use curl a lot for different purposes. Recently my
desktop (Slackware Linux - Current branch) install of curl stopped working
saying the following:

curl: (1) libcurl was built with HTTP disabled, http: not supported!

I thought that was really odd, and maybe the curl package was corrupted, so I
removed it, and downloaded the latest Slackware package. The same thing
still happened. I then thought... maybe something's wrong with the packaging
system all together with this curl problem (all other programs are working
fine... wget, etc., so I knew it wasn't a connection issue). So, I removed
the curl package again, downloaded the source and compiled it myself. I'm
still experiencing the problem, but the configure output said it was
supporting both HTTP and HTTPS. At this point I don't know what's going on.
I'm going to attach my configure output in case someone sees something I
don't.
