Bugzilla Bug 76529

When I try to emerge eclipse-sdk, I get the following errors:
/usr/lib/portage/bin/ebuild.sh: line 399: cd: /var/tmp/portage/eclipse-sdk-3.1_pre4/work/eclipse-sdk-3.1_pre4/plugins/org.eclipse.swt.gtk64/src/Eclipse SWT PI/gtk/library: No such file or directory
./build64.sh: ./build64.sh: No such file or directory

!!! ERROR: dev-util/eclipse-sdk-3.1_pre4 failed.
!!! Function build-gtk-native, Line 406, Exitcode 127
!!! Failed to build platform-independent SWT support

I looked at the ebuild and the ebuild did not fetch the swt source file from the eclipse download site. This file has to be unpacked into the appropriate plugins directory org.eclipse.swt.gtk64 and then the file swtsrc.zip which is in that directory also needs to be unpacked.

Reproducible: Always
Steps to Reproduce:
1. nano -w /etc/portage/package.unmask
2. add dev-util/eclipse-sdk~amd64 to the package.unmask file
3. emerge eclipse-sdk

Actual Results:  
Emerge picks up dev-util/eclipse-sdk-3.1_pre4 and fetches the source file and
extracts it and begins to compile the source and gives the following error:

/usr/lib/portage/bin/ebuild.sh: line 399: cd:
/var/tmp/portage/eclipse-sdk-3.1_pre4/work/eclipse-sdk-3.1_pre4/plugins/org.eclipse.swt.gtk64/src/Eclipse
SWT PI/gtk/library: No such file or directory
./build64.sh: ./build64.sh: No such file or directory

!!! ERROR: dev-util/eclipse-sdk-3.1_pre4 failed.
!!! Function build-gtk-native, Line 406, Exitcode 127
!!! Failed to build platform-independent SWT support


Expected Results:  
The softare should also have fetched the swt source for the corresponding
architecture , in my case, amd64 and extracted it and the ebuild should have
been successfully merged
