help with setup

I just set about installing sqwebmail-3.6.2 on my redhat 9
box, downloading source and building with the following
config options:

./configure --disable-changepass --enable-autopurge=14 
--enable-cgibindir=/usr/local/apache/htdocs/webmail/cgi-bin 
--enable-imagedir=/usr/local/apache/htdocs/webmail/htdocs/images 
--disable-autorenamesent

everything built fine, I did the make install-strip and set
about customizing the start/stop scripts and the one rc file
that it complained about.  sqwebmaild and authdaemond both start
with no complaints.  However, when I try to run the cgi from my
browser, I get the following error (in amoungst a bunch of other
junk...)

CGI environment exceeds allowed maximum size.

Any clues as to what I might have screwed up or how to fix this?
