No browser in eclipse?

[Mike Harding]

I am using 6.0-RC1 with a fresh build of everything. I have mozilla
already installed and built eclipse, but it says "Embedded browser not
available" and also

...
java.lang.UnsatisfiedLinkError: no swt-mozilla-gtk-3139 in
java.library.path
...

I haven't set any build flags of any kind, but I did build mozilla
before I built java or eclipse.

Any clues?
