I ran into similar issues when I tried to install ReadLine.pm and also with some other modules.

On one occasion it did get fixed on its own, when I upgraded from build 630 to 631. On other occasions I had to reinstall after wiping out perl directory.

As far as the compiled html help introduced with build 630 that has been done away in build 631. In any case you did not have to use the compiled html help, you could download a ppm for the normal html help. And rudif's Update HTML Doc is very useful if you install something directly from cpan.

What help file utility are u using?
