[gridengine users] install error

[Gerard Henry]

hello all,
we have the old SGE 6.2u5
I'm trying to compile SGE6.2u5p2, i just need the fix for the 4Go mem 
report bug.
My idea was to recompile binaries, and to replace the actual sge_execd 
with the new ones.
I follow the instructions here:
http://gridscheduler.sourceforge.net/CompileGridEngineSource.html

everything seems ok. I get:
bin/lx26-amd64/
utilbin/lx26-amd64/
lib/lx26-amd64/
and i copy these files into my existing SGE installation.

before that, the dirs were:
bin/lx24-amd64/
utilbin/lx24-amd64/
lib/lx24-amd64/

when re-starting qmaster, it uses lx26 instead of lx24 (i'm on centos ) 
but it fails, and in messages:
01/25/2012 11:50:17|  main|octopus|E|Binaries were compiled with 
spooling method "classic", requested spooling method is "berkeleydb"
01/25/2012 11:50:17|  main|octopus|E|error creating a "berkeleydb" 
spooling context
01/25/2012 11:50:17|  main|octopus|C|setup failed

why does it search for berkeleydb ? since i'm using classic spool.



thanks in advance for help,

gerard
