Update 2019-02-26: disregard my hypothesis below; I've since figured out what the issue was and addressed it in Tcl::pTk 0.95. See my newer reply.

Howdy, I was recently added as a co-maintainer of Tcl::pTk, so I wish I had come across this question earlier.

Indeed this sounds like part of the program is trying to use Tk but Tcl::pTk::TkHijack isn't loaded. Having Tcl::pTk installed does not make Perl/Tk programs automatically use it. To summarize what's documented, using Tcl::pTk with an existing program requires (from most to least effort) either:

substituting all mentions of Tk with Tcl::pTk, i.e. use Tk; with use Tcl::pTk;, any Tk::package or Tk->thing with Tcl::pTk::package or Tcl::pTk->thing, etc.;
putting use Tcl::pTk::TkHijack; (BEFORE any existing use Tk;) at the top of the program's main script;
running the program's script using the -MTcl::pTk::TkHijack command-line parameter, i.e. perl -MTcl::pTk::TkHijack my_tk_program.pl.

I find the command line parameter approach the easiest for testing an entire program without changing any code; that way I can still run it with Perl/Tk for comparison or when something breaks under Tcl::pTk. The use Tcl::pTk::TkHijack; approach has the same effect, and just that line will need to be commented out to go back to Perl/Tk. Then, for programs "ready" to be run only with Tcl::pTk (i.e. Tcl::pTk doesn't break for your program) and you don't want to use Perl/Tk anymore, then the first approach might work better.

PS: I put out a new version of Tcl::pTk recently (0.93), though there isn't any changes that would affect this findINC issue. I also added Tcl::pTk to MacPorts, which uses Tcl/Tk 8.6.8. Note that macOS comes with an older version of Tcl/Tk (8.5.9 in macOS 10.13); some improvements for macOS aqua have since been added in e.g. 8.6.8.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
