Scala Plugin and Netbeans 6.8: scala.tools.nsc.MissingRequirementError: object scala not found

Hi, I've had the latest Scala plugn working with 6.8beta and rc1/rc2 and it works fine with the release version, which is what I use now.

I don't recall needing to add jars to the project like that,
just download and unpack the plugin,
install it through the plugin manager,
probably restart the IDE
ensure scala is configured (nb -> tools -> options -> scala platforms), I'm using scala-2.8.0.Beta1-RC2 which seems to work fine
create a new scala project and add say an object with a main that println's hello world and run it and it should be fine

What version of Scala are you using with it?

I'm trying to use the newly released Netbeans 6.8 with the Scala plugin "nb-scala-6.8v1.1.0rc1", but am consistently getting the following error whenever I try to clean and build any Scala code. I have added the Scala jar files at the project -> properties -> library option, but that makes no difference.
I've also tried the plugin with Netbeans 6.8 rc2, but get the same error. 
Has anyone successfully used Netbeans 6.8 (released version or rc2) with the latest Scala plugin?
I've also posted this issue https://netbeans.org/bugzilla/show_bug.cgi?id=178743 to the netbeans website, but have no responses yet.

I am using the plugin during last three months with big pleasure :-)

Have you set up $SCALA_HOME? Is $SCALA_HOME/bin in your PATH?

I've installed the Scala "nightly build" (scala-2.8.0.r20145-b20091216020133.zip) and the Netbeans Scala plugin (nb-scala-6.8v1.1.0rc1.zip), on top of Netbeans 6.8 (release version). The attached image shows the details -- along with a source module I'm attempting to compile, and the error message.
What else can I check?

Yes, I have $SCALA_HOME and $SCALA_HOME/bin set correctly, I can verify those separately from a command window.
What else can I check?

Does Tools -> Scala Platforms show something found?

Probably (being using windows) you can try to use all needed paths without
spaces.

Thanks Andrew,
That helped! I moved the Scala install directory from "C:\Program Files\Scala-2.8.0" to "C\Scala-2.8.0" (a path without spaces) and everything seems ok now.
Thanks all for your help.
