With the patches to tcl and tk (8.4.6) which allow them to build on MacOS X,
I've started building the packages which depend on them.

While building devel/libstroke (a dependency of cad/geda), the build
failed as follows:

[...]
 gcc -DHAVE_CONFIG_H -I. -I.. -I../include -I/Volumes/NetBSD/pkgsrc/devel/libstroke/work/.x11-buildlink/include -no-cpp-precomp -I/Volumes/NetBSD/pkgsrc/devel/libstroke/work/.buildlink/include -O2 -c tcl.c -o tcl.o >/dev/null 2>&1

*** Error code 1

Although the dependency checks for libstroke consider the current tcl
(8.4.6) to be satisfactory:

[...]
=> Checksum OK for libstroke-0.3.tar.gz.
===> Extracting for libstroke-0.3nb1
===> Required installed package tcl>=8.3.4: tcl-8.4.6nb3 found
[...]

there appears to be some further part of the mechanism which assumes that
tcl83 (8.3.4) will be used.

I see that the pkgsrc Makefile explicity references:

    lang/tcl83/buildlink3.mk

Perhaps re-trying the build with this changed to the current tcl's
buildlink3.mk file will fix this?
