Remember, htdig acts as a web client and determines the parser
to use according to MIME type, not extension. If the server
claims .phtml files are of the type "text/html", then that
is what htdig uses.

Couldn't you just add .html and .phtml to the exclude_urls
configuration option in htdig.conf?

If you want to put it in a configuration file, that is another
possibility. But shouldn't the plug-in know what MIME types it
can handle? What if the user tries to use the text
module to parse a Frame (or Word file)? The index will be
filled with garbage, wouldn't it? I'm not sure, I'm guessing.

I will have to look at the documentation before commenting but
does libc6 replace libc? And if it does, would that mean libc
would have to be replaced on the system to compile and run
htdig? If it does, then I don't think that will fly.

Adobe FrameMaker, a Desktop Publishing tool. FrameMaker was
actually created by Frame Technologies, which was bought by
Adobe. A competing product is InterLeaf.
