Comment 12 for bug 195772

I tried to follow the compilation directions provided above. Unfortunately, I'm still having problems. Here is the output I get:

me@my-computer:~/Downloads/matplotlib$ sudo apt-get build-dep matplotlib
Reading package lists... Done

me@my-computer:~/Downloads/matplotlib$ dpkg-source -x matplotlib_0.91.2-0ubuntu1.dsc

gpg: Can't check signature: public key not found
dpkg-source: failure: cannot read ./matplotlib_0.91.2-0ubuntu1.diff.gz: No such file or directory

I can't continue since there is no directory to CD into.
