Hi, I just spent a while trying to figure out how to get R png graphics to work again in Sage-6.2rc0 on Ubuntu 14.04. Note that graphics worked fine with Sage-6.2beta1 on Ubuntu 12.04. Karl Dieter's many random posts around the web asking about this problem were helpful, though in this case the problem is new in sage-6.2rc0 due to trac #15742, and will kill R usage for a lot of people if we release sage-6.2.rc0 as is...
I tracked the problem down to pkg-config being in Sage-6.2rc0, whereas it is not in Sage-6.2beta1. This is because of http://trac.sagemath.org/ticket/15742, which is very important to getting Sage to build at all on some wonky systems. But on a mainstream modern Linux OS this ticket leads to problems. Wouldn't it be better to only build/install pkgconfig on systems that don't have a good one already? My solution to deal with this R problem is: cd $SAGE_ROOT/local/bin && mv pkg-config pkg-config.orig && ln -s /usr/bin/pkg-config . sage -f r Of course, I have to wonder what other components of Sage got built incorrectly due to Sage's pkg-config returning misleading results (e.g., saying that a system-wide library isn't available even though it is)...
