1.5.2

any clue what's going on & how to get png ...

I installed from source . wasn't aware of any PowerPC Mac binary.

I just went through the "painful" process of installing ImageMagick and all it's dependencies on a PowerPC Mac (OS X Server 10.5.8).

Now trying to see if convert will work I run it and it hangs.

$ convert test-image.jpg test-image.png
