Experiencing the same problem after installing Python (x,y) version 2.7.5.2

The interpreter is answering "ImportError: matplotlib requires pyparsing" 
when trying to interpret the line "import matplotlib.pyplot" of my source code.

If you have easy install available, the easiest thing to try (in Windows) is to 
open a dos command prompt line and to type "easy_install matplotlib". 

That installed the program with the version I needed to get it up and running 
with Python X,Y. 

If that doesn't do it, I'm not sure what the best method would be...

See bug 694. pyparsing is erroneously not checked in the installation by 
default.

Should be fixed in 2.7.6.0 - out now.

Cheers!
