i have a very similar problem.

i am getting this error when Mathematica checks for SGE initialization.
Java::excptn: A Java exception occurred: java.lang.UnsatisfiedLinkError: no drmaa in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1753)
	at java.lang.Runtime.loadLibrary0(Runtime.java:822)
	at java.lang.System.loadLibrary(System.java:993)
	at com.sun.grid.drmaa.SessionImpl$1.run(SessionImpl.java:64)
	at java.security.AccessController.doPrivileged(Native Method)
	at com.sun.grid.drmaa.SessionImpl.<clinit>(SessionImpl.java:62)
	at com.sun.grid.drmaa.SessionFactoryImpl.getSession(SessionFactoryImpl.java:60).

i have this configuration
/etc/profile:
-------------------
#SGE VARIABLES
source /common/default/common/settings.sh

#add PATHS
export PATH=/opt/openmpi-1.4.1/bin:/usr/local/bin:/common/bin/darwin-x86:$PATH
export CLASSPATH=/common/lib/drmaa.jar:/common/lib/jgdi.jar:/common/lib/juti.jar

export LD_LIBRARY_PATH=/opt/openmpi-1.4.1/lib:/common/lib/darwin-x86/:$LD_LIBRARY_PATH

#aliases
alias math='/Applications/Mathematica.app/Contents/MacOS/MathKernel'
-----------------

and on the cluster integration window i have this parametersMathematica Config:

Cluster Name = cfc
Cluster engine = Sun Grid Engine
Head node = mac-pro-3.local

Advanced Settings:
Engine Path = /common (Which is the same as $SGE_ROOT)
Kernel Options = -subkernel -mathlink -LinkMode Connect - LinkProtocol TCPIP - LinkName "linkname'
Kernel Program = /Applications/Mathematica.app/Contents/MacOS/MathKernel
Native specification =
Network Interface =
Queue job = Global`true

-

It seems that it cannot find DRMAA, but i have set the Enviroment Variables...
or is it different in mac OS Leopard???
