[Rivet] lhapdf path

[Gavin Hesketh]

Hello,
I'd like to use lhapdf along with my agile install. I've successfully 
installed everything, and (eg) pythia can now find the PDF sets as 
needed. My only problem is that the path to the PDFs ends up being the 
full path at time of installation, which is fine for an interactive 
session but inevitably wrong for a batch job.

eg:
==============================================
  PDFset name 
/home/ghesketh/bar/rivet/local/share/lhapdf/PDFsets/MRST2007lomod.LHgrid
  with          1 members
====  initialized. ===========================

This must be set by a call of SetPDFPath, but I have not found where in 
the code this is. Having spent enough time looking, it seemed worth 
asking if anyone else had the same problem. I'm assuming this is an 
AGLIE issue, but am not sure...

thanks,
	Gavin
