[horde] Problem getting latest horde to work

[Loren Koss]

I have been using Horde/Imp for quite some time, but yet am really
struggling with the latest version.  The version I have working is running
on an old FreeBSD 4.1 box, so I thought maybe I should upgrade.  I have a
pretty much clean install of 6.1 with PHP 5.2.1 and Apache 2.2.4.  I can
get the login screen to come up and if I enter a bad password it does
return with login failed (though it does take a minute or so which seems
awfully long), but a valid password eventually brings up a blank page and
this message in the apache error log:

child pid 14268 exit signal Illegal instruction (4)

I've done tons of searching online to find out a reason for this, but all
the posts have been regarding older versions of php and apache that have
to do with multi-threading problems.  Not sure that its related.  Any help
would be appreciated.  Perhaps I didn't build something right.  Here is my
config for PHP:

Configure Command =>  './configure' '--with-apxs2' '--with-gettext'
'--with-dom' '--with-mcrypt' '--with-imap' '--with-iconv'
'--enable-mbstring=all'
'--enable-mbregex' '--with-gd' '--with-png-dir=/usr' '--with-jpeg-dir=/usr'
'--with-mime-magic' '--with-zlib' '--with-mysql' '--with-curl' '--with-openssl'
'--with-mysql=/usr/local'

Do you need more info?  Just let me know and I'll get whatever is
necessary - I really want to upgrade to the latest version.

Thanks
