pana fails checking the screenshots

[isoos]

I think you don't have the webp command line tools installed. On Debian/Ubuntu it is done via apt install webp.

Thanks, that's correct, the message wasn't clear though

@szakarias: can we easily detect if the tools are installed?

[sigurdm]

I think we are detecting this:

pana/lib/src/screenshots.dart

Line 395 in eb444dd

stderr.write("'${cmdAndArgs[0]}' tool not found.");

.
We should probably use writeln instead of write.
