PDF::FromHTML subroutine not found

jonnyfolk has asked for the wisdom of the Perl Monks concerning the following question:

I've installed PDF::FromHTML. On running I get Error:


Undefined subroutine &PDF::FromHTML::HAS_HTML_TIDY called at /usr/loca
+l/lib/perl5/site_perl/5.8.8/PDF/FromHTML.pm line 124.
[download]

I've had a look at the source and installed all related modules. Can any one shed some light on this?

A similar bug has been recorded 11 months ago. Looking at the source (and showing my findings...), I don't readily see what causes this behaviour. The relevant pieces of the code are: `use constant HAS_HTML_TIDY => do { local $@; eval { require HTML::Tidy; 1 } or do { unless ( eval { require XML::Clean; 1 } ) { die( "Please install HTML::Tidy (preferred) or XML::Clean +first" ); } 0; # Has XML::Clean but no HTML::Tidy }; }; ... sub parse_file { ... if (HAS_HTML_TIDY()) { }` [download] It seems to me that the `use constant` does somehow not have the effect of declaring `HAS_HTML_TIDY`, but I don't see how that happens. Do you have HTML::Tidy installed? Also, as you seem to be running the system Perl, how did you install the module? Did you use your vendor's package manager?	[reply] [d/l] [select]

Your hunch turns out to be correct, thank you. HTML::Tidy is now installed, and the module is creating PDF. Perhaps the only 'bug' is a slightly misleading error message? :)	[reply]

I'm running VPS and used the cpanel install service. HTML::Tidy is not installed and interestingly the install failed! I've requested installation for that.	[reply]
