It is very fast! Thank you. This solves my problem!

allows, indirectly, to reuse features from a GPL program to supplement a
commercial one. Philosophically speaking, I am against such a practice.
However, this is, and should remain my own opinion... Now

the case), is it OK to support such plugins or GUIs that possibly violate
the GPL license, for instance, by distributing them, or by placing links to
them in the R GUI Projects web site?

I suppose that such a complicated construction of "ind" had some meanings in

I would recommend to contact the package maintainer and ask for an
update for version 2.1.0 of R. In the meantime, you should continue to
use R 2.0.1 with limmaGUI, if you really need the GUI.

http://www.murdoch-sutherland.com/Rtools/, you can read that R 2.1.0 was
(probably?) compiled using libpng-1.2.5.tar.gz, i.e., the latest stable
version. You could try libpng-1.2.6 to see if it solves your problem.
