removing file doing uninstall

[Carmel]

How do I remove a file from an older release that is no longer in the
newer release.

Assume:

"Release.html" is in the older port version. In the newer port version,
it has been replaced by "Release.pdf".

I tried placing this in the "pkg-plist"file.

@unexec if %%PORTDOCS%%%%DOCSDIR%%/Release.html; then rm -f %%PORTDOCS%%%%DOCSDIR%%/Release.html; fi

However, while "portlint -A" has no problem with it, I receive:

share/doc/scamp/Release.html: not found
pkg_delete: unable to completely remove directory

when running "make deinstall"

@unexec if %%PORTDOCS%%%%DOCSDIR%%/Release.html; then rm -f %%PORTDOCS%%%%DOCSDIR%%/Release.html; fi
