Thanks Christoph, thanks for the help.
However I found the issue.
The issue is that somehow matplotlib_release variant linked to the debug lib of libpng.
And so on a non-developer machine, which dosent have msvcr90d.dll (debug crt), DLL Load fails.So now I have another question:
I have built the static libs of freetype, libpng (and zlib which is required by libpng) from source
And I mention the paths of these static libs in setupext.py (by modifying “basedir”) while building matplotlib.Now when matplotlib builds, and generates a _png.pyd, will it still need the static libs to be present in the location where the _png.pyd is present?
What I understand is that it shouldn’t since it is a static library and should be built into the binary.Why I am asking this is because I am unable to build the libpng DLLs (for some reason I dont know).
So I have to go forward with the static lib approach.Thanks,

Tej.Hi,
I built matplotlib1.2.0 with python3.2 on Windows7 from source.
I built the libpng and freetype libs and linked them statically to
matplotlib.
Everything works fine on my machine, I can run the matplotlib examples etc
But on a new Win7 machine(with the exact same configuration as mine,
except a few softwares), I get the following error when i try to import
png module like this:
import matplotlib._png
ImportError: DLL load failed: The application has failed to start
because its side-by-side configuration is incorrect. Please see the
application event log or use the command-line sxstrace.exe tool for more
detail.
I used the dependency walker and found that pyd_ DLL was indeed having
issues during load.
What could be the reason. Surprisingly it works all fine on my machine.
Regards,
Tej
Assuming this is 32 bit Python, install the Microsoft Visual C++ 2008
Redistributable Package (x86) <from
Besides that, look for extra msvcp90.dll or msvcr90.dll files in PATH
(for example MikteX is known for that) and resolve conflicts.
