First of all sorry if this has been already solved but although I found a couple of messages dealing with the same issue in the archives, I have not found an answer. The fact is that I'm running Gretl 1.5.1 on Mac OS X (by using the script gretl.sh in the bin folder) but I cannot make plots. When I try to, the following message pops up ==== yld: Library not loaded: /System/Library/Frameworks/ ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/ Versions/A/Resources/libPng.dylib Referenced from: /System/Library/Frameworks/ ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/ Versions/A/ImageIO Reason: Incompatible library version: ImageIO requires version 1.0.0 or later, but libPng.dylib provides version 0.1.2 ==== I wonder if anyone could give a hint about the underlying problem. Thanks
