matplotlib-0.98.5.3 Configure error - Build fails when Tkinter missing

[hans.ekkehard.plesser@…]

I tried to install matplotlib issuing

sudo port install matplotlib

and ended up with the following error message

--->  Building py25-matplotlib

The error did not disappear after installing py25-tkinter and tk. Installation worked when deactivating tkinter variant with -tkinter`.

There is no "matplotlib" port. The first command returns an error for me. I assume you meant py25-matplotlib?

What is the result of the following?

port installed python25 python_select

and if installed:

python_select -s 

[skymoo (Adam Mercer)]

py25-tkinter is now just a stub as tkinter is included in python25. What OS and architecture is this on? I can't reproduce this on Intel Leopard:

$ port installed python25 py25-tkinter py25-matplotlib
The following ports are currently installed:
  python25 @2.5.4_5+darwin_9+macosx (active)
$ sudo port install py25-matplotlib

The default backend is now the non-interactive Agg backend, different
backends can be specified using the ~/.matplotlib/matplotlibrc file.
More details, regarding backends, can be found in the matplotlib FAQ:

Can you run

$ sudo port clean py25-matplotlib
$ sudo port -d install py25-matplotlib

and attach the output to this ticket?

Make sure your python25 port is up to date (2.5.4_5 is current).

Apologies for my sloppiness. Yes, I meant py25-matplotlib.

What is the result of the following?

port installed python25 python_select

vpnans-68:~ plesser$ port installed python25 python_select
The following ports are currently installed:
  python25 @2.5.2_5+darwin_9
  python25 @2.5.4_0+darwin_9+macosx (active)
  python_select @0.2.1_0+darwin_9 (active)

and if installed:

python_select -s 

vpnans-68:~ plesser$ python_select -s
python25

After updating to python25 @2.5.4_5, everything works fine. So it seems my slightly outdated python25 @2.5.4_0 was the cause of the problem. But that was not easy to guess from the error message I got. Btw, my system is Leopard 10.5.7.
