I have installed Tcl and Tcl::Tk from CPAN.
On my linux machine “Hello world” example from Synopsis of the documentation runs fine.
On my Mac a window is drawn, but it does not come into foreground (does not take focus) and its content is empty. No error is written to STDERR and the process must eventually be killed.

I have tried this with numerous example scripts,
with Tcl::Tk or with Tkx,
with ActiveTcl or Tcl/Tk Aqua (http://tcltkaqua.sourceforge.net/)
with pre-installed perl5.8.1 or with perl5.8.8 (from DarwinPorts).
Result is always the same. Pure Tcl/Tk scripts from Wish run just fine, non GUI perl scripts with ‘use Tcl;’ also work.

Any suggestions?

Thanks, Pavel
