post-install spamassassin debug yields nothing

[Dan Carl]

First of all I've been a happy Mailscanner user for several years now thanks
for the great software.
I started getting more spam so I decided to upgrade to:
MailScanner Version Number = 4.54.6
SpamAssassin version 3.1.2

The upgrade seemed to go fine but now when I issue the command:
spamassassin -D -lint -p /etc/MailScanner/spam.assassin.prefs.conf
Nothing happens, I have to ctrl C to get back to a prompt.
If I issue the command:
spamassassin -D
it gets a far as here
[32085] dbg: dns: Net::DNS version: 0.57
and stops
If I run analyze_SpamAssassin_cache
--------- TOTALS ---------
Total records:       286
