Eclipse CDT Linux ClearCase SCM Adapter plug-in install problems

I'm having a silly little problem with Eclipse. I'm trying to install Rational ClearCase SCM adapter in Eclipse (Helios SR1) CDT Linux 64 bit. I downloaded ClearCase plug-in form here. I tried both SCM adapter version 7.0.0.2 and 7.5.0.0. I got this error in both case?

Cannot complete the install because some dependencies are not satisfiable com.rational.clearcase.linux.feature.group [7.0.0.20081031A] cannot be installed in this environment because its filter is not applicable开发者_StackOverflow社区.

My clearcase version is not exactly the same as the adapter. Is this why? In this case, where can I dowload SCM adapter for v 7.1 ?

linuxcc7$ ct -version
ClearCase version 7.1.0.00 (Tue Nov 11 00:18:47 EST 2008) (7.1.D081110)
@(#) MVFS version 7.1.0.0 (Mon Oct 13 20:06:10 2008) built at $Date: 2010-11-12.14:19:20 (UTC) $
cleartool         7.1.0.0 (Sat Oct 25 22:52:22 2008) 
db_server         7.1.0.0 (Sat Oct 25 22:53:08 2008)

I have no idea what filter is it complaining about. Any ideas?

Many thanks.

IBM support says that SCM Adapter is not officially supported on 64 bit operating system. Check here for a workaround on non-Windows installation

Older version of Eclipse, also on Linux 32 still have problems with IBM Rational Clearcase plugin 7.x.

Finally I end up using open source plugin, install straight forward and works very well.

Note: After installing the open source plugin, make sure you restart the eclipse. Also after creating a new project or project from existing source, make sure you associate the project with ClearCase. (Choose Team-->Associate With ClearCase in Project context menu)

I am not sure the Eclipse CDT package is the most suited one for ClearCase plugin.

I tried a classic RCP Eclipse package, both with the update site, or externally with a shared dropins, each time successfully.
