Replying to [comment:4 kcrisman]:
> Hmm, that's bad. We include libpng as part of Sage, as far as I know
(libpng-1.2.35.p2.spkg). So somehow R wasn't picking up the Sage copy of
libpng. That is very interesting. And bad.

Using Sage 4.6.1.alpha0 on my !OpenSolaris 06/2009 machine, I just run
those two commands given on ask.sagemath.question:
{{{
sage: r.eval('capabilities("png")')
' png \nFALSE '
sage: r.eval('capabilities("X11")')
' X11 \nFALSE '
sage:
}}}
looks like I have neither PNG or X support built in. This is odd. When I
check {{{spkg/logs/r-2.10.1.p4.log}}} I see:
{{{
checking if libpng version >= 1.0.5... yes
}}}
then later
{{{
R is now configured for i386-pc-solaris2.11
Source directory: .
Installation directory: /export/home/drkirkby/sage-4.6.1.alpha0/local
C compiler: gcc -std=gnu99
-I/export/home/drkirkby/sage-4.6.1.alpha0/local/include
-L/export/home/drkirkby/sage-4.6.1.alpha0/local/lib/
Fortran 77 compiler: sage_fortran -g -O2
C++ compiler: g++ -g -O2
Fortran 90/95 compiler: sage_fortran -g -O2
Obj-C compiler:
Interfaces supported:
External libraries: readline
Additional capabilities: PNG, JPEG, TIFF, NLS
Options enabled: shared R library, shared BLAS, R profiling,
Java
Recommended packages: yes
}}}
So despite PNG support apparently built in,
{{{r.eval('capabilities("png")')}}} indicates otherwise.
It's difficult to know what to trust.
