Comment 9 for bug 1248254

As far as I can see, i8kmon doesn't require some specific version of Tcl or Tk. At the same time, since a long time ago, the default version of Tcl and Tk is 8.5, and i8kutils depends on a default version. Apparently, your system still has the old version of tcl package which pulls tcl8.4, or your system is somehow else misconfigured.

Summarising, this doesn't seem like a bug in the package to me, no. The only thing I'd probably do is to remove strict Tk version requirement, it's really not necessary. Also, it's better to use /usr/bin/env tclsh as the shebang, not /bin/sh + exec tclsh magic. In that case, MAKE_LINTIAN_HAPPY trick isn't needed either.
