Hello, I thought all my gretl issues were gone but now gretl is coming up with some new error messages. I can't do any type of plots. It says "gnuplot command failed" and in the xterm window I get the following: dyld: 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 Failed command: 'gnuplot "/Users/adri/gretl/gpttmp.sifTVB"' Unknown error:0 Anybody who can help me ? thanks...
