Hi,

I have a problem on my mac when trying in R to produce png images.

I am getting this warnings with the ArrayQualityMetrics package:

arrayQualityMetrics(rma_fatBody, outdir="normData", force =T)
The report will be written into directory 'normData'.
KernSmooth 2.23 loaded

libpng warning: Application built with libpng-1.2.26 but running with 1.5.2

libpng warning: Application built with libpng-1.2.26 but running with 1.5.2

I am running the R 2.14 version using the R studio GUI.

I am not excatly sure about the libpng problem. When I am doing locate
libpng-config I'm getting several hits, some with libong-config12, some
with libpng-config14, some without nay numbers:

ayeroslaviz:~ ayeroslaviz$ locate libpng-config
/Applications/XAMPP/xamppfiles/bin/libpng-config
/Library/Frameworks/GTK+.framework/Versions/2.18.X11/Resources/bin/libpng-config
/opt/local/bin/libpng-config
/usr/X11/bin/libpng-config
/usr/local/bin/libpng-config

When doing which libpng-config I'm getting: /usr/local/bin/libpng-config

Is there a way to uninstall older versions of libpng or update the paths to
the right version. Unfortunately I am not even sure, what thesource of this
warning, so I hope I gave here all the needed information.

I would be grateful for anyone who gives me a hint about how to solve this
problem.

thanks

A.
