Actually, Ole answered your questions on the saga-users
mailing list, about two days ago.  In case you missed that
mail, it is attached here again.

Best, Andre.

Hey Ye,

Nope. You need to have the Globus header and libraries installed in  
order to build the SAGA preWS GRAM adaptor. Have a look at the  
installation manual in the docs directory.

You need GT in advance ;-)

We currently have job service adaptors for

* Globus preWS GRAM
* OMII GridSAM
* Condor
* Platform LSF (will be part of SAGA 1.1 - to be released in a couple  
of days)

I don't know if it is possible to build a self contained GRAM package.  
I guess so - I mean you could just build the GRAM client libraries  
and, let's say grid-proxy-init. Ask the Globus guys how this works ;-)

Well, actually we use C++ in all our examples. The API wrappers we  
currently have for our C++ reference implementation are Python  
(working) and C (not yet working).

I don't know about the status of the SAGA Java implementation. Maybe  
one of the Java guys on this list might be able to help?!

Hope that helps.
