One thing was missing though - under Linux I found that the default gflashplayer executable didn't exist. Instead, we have a different flash player available as part of the project tree. But there was no way to override the default used by the FlexUnit's launcher class and changing PATH variable in Ant is just a bear.
So, to make a long story short, I added ability to specify flashPlayerCmdPattern argument to the flexunit ant task. In the process, I created a GenericLauncher class based on the MacSWFLauncher (which looks to be generic enough and the most up to date).
Works like a charm. One possible enhancement for someone who knows Ant better - ability to specify the flash player as inner task element (with the <env> and <argument> tags and whatnot). But this worked well enough for me.
Here's the patch that goes with FlexAntTasks-src.zip from 2008-02-18. Enjoy!
