Can not enable calendar module

Trying to enable the calendar module leads to the white screen of death. I've read all of the forum posts on any of those keywords, along with those for views and dates, but still no joy.

I have Drupal 4.7 installed on a dedicated Linux box, running Apache 2.0, MySQL 4.1, and PHP 4.3. I have installed (several times) the following modules: calendar, date, and views.

Per the forum posts, I have removed half a dozen modules from the site which are not being used. I have also increased memory limits to 16M, 32M, 64M, and even 128M -- and verified those changes via phpinfo -- but without any impact.

The best I've done so far is to have:
a, calendar installed (but not enabled, since that requires date and views)
b. date installed with both date and date_api enabled
c. views installed with both views and views_ui enabled

But then, when I try to enable calendar, I get the white screen of death. The only way I've found to bring the site back up is to remove the views module from the server.

It appears that a lot of folks have had similar issues. Is there a solution that I've not come across yet?
