Pencil  is an animation/drawing software for Mac OS X and Windows. It lets you create traditional hand‑drawn animation (cartoon) using both bitmap and vector graphics. Pencil is free and open source.

I wanted to run it under Linux (without wine ) so I tried to compile:
Get mac version of source
wget http://www.les-stooges.org/pascal/pencil/contents/Download/pencil-0.4.2b-mac-src.tgz
tar xvfz pencil-0.4.2b-mac-src.tgz
cd pencil-0.4.2b-mac-src

Use local version of ming library
Edit pencil.pro and change LIBS to:
LIBS += -lming

and remove binary verison of libming.a with:
rm lib/libming.a

You will also have to comment out one line in src/interface/editor.cpp
                updateMaxFrame();
//              object->exportMovie(1, maxFrame, view, exportSize, filePath, fps);
                return true;

Build it
Create Makefile and build project:
qmake-qt4
make

All required changes to source are also available as single diff file: pencil‑0.4.2b‑linux.diff

After compiling it, I went to Google and searched for exportMovie (it's easy once you know what to do :‑) and found following blog post  which had reference to same fix for compilation (I didn't need ‑lungif to make it work)
