py26-matplotlib: You must install numpy 1.1 or later to build

[info@…]

I'm running the command: sudo port -d install py26-nltk

And it's failing to build with py26-matplotlib and py26-yaml left as dependencies. Debug log is attached. Thanks for any insights!

The relevant error in your log appears to be "You must install numpy 1.1 or later to build". py26-numpy is declared as a dependency of py26-matplotlib. Is py26-numpy installed and active?

I assumed it was installed and active because I ran the whole thing, and it only listed py26-matplotlib and py26-yaml as remaining dependencies. What's the best way to check?

I saw that the MacPorts process also installed another version of python, and there was a message about switching to use that version - is that the one that I need to use? Should I also not have a PYTHONPATH set, would that mess up the install?

What do you mean by "need to use"? The python_select script just creates a python symlink pointing to the specified python version. Whether you run that command or not should have no effect on matplotlib being able to find NumPy. I would guess that theres some problem with your NumPy installation.

Should I also not have a PYTHONPATH set, would that mess up the install?

The modules are installed in the default location for where python is installed so you do not need to set PYTHONPATH.

During the build of matplotlib it simply tries to import the numpy module, if that fails it returns the error message to you quote above. Does the following command return any output:

$ /opt/local/bin/python2.6 -c "import numpy"
$

Assuming you're prefix is /opt/local, the command should run for a while and then return to the prompt.

Damn, should proof read after changing wording :-(

You've installed another NumPy, a 32bit version, into your home directory so this is getting picked up. Remove this and you should be good. As another option you can place the MacPorts location in the PYTHONPATH ahead of this version, but I would advise simply removing this home directory installation as it's going to cause further problems down the line.

That did it! Thanks for the translation of the error messages! :)
