What version of Apache? I tried 2.0 a month or two ago and there was no libapreq generally available that worked. There was one posted somewhere that some said they got working but the Apache guys on the libapreq mailing list said it would be best to stick with the 1.3 path for a while if I needed a stable, working libapreq.

The disclaimer here is that I haven't gotten back to that for a few months so a lot may have changed.
