Bryan, thanks for the response.
I installed macports and the environment settings seem to be correct, but when
I try "port help selfupdate" I get:
/opt/local/bin/port: line 4: /usr/bin/tclsh: No such file or directory
/opt/local/bin/port: line 4: exec: /usr/bin/tclsh: cannot execute: No such file
or directory
I removed the installation of Tcl 8.6 and reinstalled ActiveTcl 8.5.10, but
still get the same warnings.
Matplotlib is now complaining about the missing Tcl8.6:
ImportError:
dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/_tkagg.so,
2): Library not loaded: /Library/Frameworks/Tcl.framework/Versions/8.6/Tcl.
I am assuming that your unsuccessful install via macports was after you had
macports working; do you know what version of Tcl was installed?
Macports fails with the same warnings after putting a link to tclsh8.5 in
/usr/bin/tchsh.
I still seem to be running in circles.
