Bugzilla Bug 237973

If eclipse-sdk-3.4-r2 is installed with swt-3.4_pre6-r1, Eclipse will not start
complaining of not being able to create a configuration file.

The symptom of this was reported in bug 236407, but not the cause which I have
discovered after much messing around.

Reproducible: Always

Steps to Reproduce:
1.emerge dev-util/eclipse-sdk-3.4-r2
2.(with dev-java/swt-3.4_pre6-r1 installed)
3.

Actual Results:  
The package merges fine, but eclipse-sdk fails after the splash screen
complaining of not being able to create a configuration file.

Expected Results:  
Eclipse-sdk starts and runs as intended.

If the dependency on dev-java/swt is further refined to exclude
dev-java/swt-3.4_pre6-r1 and the require 3.4 and above, this could save someone
else a lot of messing around.

Fixed by removing old swt ebuilds.
