problem building compiler with nb 6m10

[Per Bothner]

I checked out the OpenJDK Subversion repository, and then
followed the instructions in
http://nb-openjdk.netbeans.org/get-and-build-compiler.html

I get:

Warning: falling back to building against /home/bothner/Java/jdk1.6.0
Please define bootstrap.jdk=.../recent/jdk7/snapshot in 
/home/bothner/.openjdk/build.properties or 
/home/bothner/Java/jdk/j2se/make/netbeans/compiler/nbproject/private/build.properties
check-javac.isuptodate:
build-lib.javac.jar:

/home/bothner/Java/jdk/j2se/build/linux-i586/bootclasses
/home/bothner/Java/jdk/j2se/make/netbeans/common/shared.xml:170: The 
following error occurred while executing this line:

/home/bothner/Java/jdk/j2se/make/netbeans/compiler/${src.classes} not found.
BUILD FAILED (total time: 0 seconds)

This is on a GNU/Linux (Fedora 7) system.

While the instructions for building the whole JDK talk about
needing binary classes, I was hoping I could just build the
compiler with jdk 1.6.  The instructions suggest I can do that.
