I am currently developing a liferay theme, but when compiling one of the SCSS files, I get the following error:
[java] Sass::SyntaxError: Invalid CSS after " @each $key": expected "in", was ", $num in $map {"

I am using Liferay 6.2 EE GA1, and this error from what I have read, can possibly be fixed by upgrading the SCSS compiler (ruby gem). However, I have -no- clue how to even approach that. It is using the ant builder (build.xml).
If I can either fix the error above, or upgrade the compiler (or both?) it would be great!
If you want to manually upgrade the SASS version, you could re-set the scripting.jruby.load.paths property. Please have a look at 6.2 Portal Properties. So you are not using classpath or java.io.tmpdir but a different folder instead. However, i did not test this, and maybe something else will fail with this upgrade (also you need a concept about CI build).
