Hi After upgrading to tcl/tk 8.5.0 I'm getting the following error when trying to build py25-matplotlib DEBUG: Assembled command: 'cd "/opt/local/var/macports/build/_Users_ram_opt_macports_python_py25-matplotlib/work/matplotlib-0.90.1" && /opt/local/bin/python2.5 setup.py build' Traceback (most recent call last): File "setup.py", line 249, in <module> tk = Tkinter.Tk() File "/opt/local/lib/python2.5/lib-tk/Tkinter.py", line 1638, in __init__ self._loadtk() File "/opt/local/lib/python2.5/lib-tk/Tkinter.py", line 1658, in _loadtk % (_tkinter.TK_VERSION, tk_version) RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.4) Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_Users_ram_opt_macports_python_py25-matplotlib/work/matplotlib-0.90.1" && /opt/local/bin/python2.5 setup.py build " returned error 1 Command output: Traceback (most recent call last): File "setup.py", line 249, in <module> tk = Tkinter.Tk() File "/opt/local/lib/python2.5/lib-tk/Tkinter.py", line 1638, in __init__ self._loadtk() File "/opt/local/lib/python2.5/lib-tk/Tkinter.py", line 1658, in _loadtk % (_tkinter.TK_VERSION, tk_version) RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.4) could it be trying to link against the system tcl/tk? $ port installed | grep "^ t" tcl @8.5.0_0 (active) tk @8.5.0_0 (active) $ Cheers Adam
