Currently with trying to compile the tcl extension with 1.9.1

I get

cl/include/tcl7.6... yes
checking for tk.h... yes
checking for Tcl_FindExecutable() in -ltcl8.4... no
checking for Tcl_FindExecutable() in -ltcl84... yes
checking for Tk_Init() in -ltk8.4... no
checking for Tk_Init() in -ltk84... yes

[it is found]

however with trunk I get

Search tclConfig.sh and
tkConfig.sh...........................................................................

Search Tcl library.checking for Tcl_FindExecutable() in -ltcl... no

[it doesn't try the other options].

Is this expected?

Does anybody know how to get it to build with ActiveTcl from trunk?
(Even reading the readme I'm at a loss).

[also as a note, I had to tweak the paths after creating the

/Tcl/lib => /c/Tcl/lib or c:/Tcl/lib
to get make to work appropriately.

And a question:
When I install tk "after the initial installation" (like a gem) when
ruby exits it fails to exit. Sound familiar to anyone?

Thanks.
