Hello, This is a good moment to ask all others (who rely upon libpng as a dep for R) to report, if they have the png capability TRUE - if so, kindly supply your easyconfig, somewhere!

The fact that the OS-provided libpng yields the capability but, *not* the EB-provided one, yes that’s unexpected and calls for more scrutiny. > Also, since R-3.2.x, if I tried install.packages() I got an error saying > "internet routines cannot be loaded".

Quite clearly, this calls for one more dependency to be defined - as regards 3.2.x; cURL easyconfigs are already there.
