sqwebmail configure loops

[Qmail]

Hi Folks,

I'm trying to build sqwebmail-2.1.0.

Unfortunately when I run: ./configure --with-htmllibdir=/var/www/html
--with-module=authvchkpw --enable-webpass=vpopmail --enable-webpass=yes

The config process just loops, and loops, and loops. It never stops. 

I tried 2.0.0 as well, same problem. 

I'm running a pretty stock version of RH 7.1, and everything else configures
and compiles fine.

Any tips?

Lance
