See code above:
/usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/javac
with:
$ ls -la /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/javac
lrwxrwxrwx 1 root root 12 2006-10-20
17:04 /usr/lib/jvm/java-1.4.2-gcj-4.1-1.4.2.0/bin/javac -> /usr/bin/ecj

How?
$ /usr/bin/ecj -target 1.4 -source 1.4 -target 1.4 -source 1.4 -classpath
src/JRI.jar -d examples examples/rtest.java
Gives:
duplicate target compliance setting specification: 1.4
where:
$ /usr/bin/ecj -version

Actually, instead of commenting out that line in Makefile.all, you can also
just remove the $(JFLAGS) to get:
examples/%.class: examples/%.java src/JRI.jar
$(JAVAC) -classpath src/JRI.jar -d examples $<
The first "-target 1.4 -source 1.4" is part of the $(JAVAC) var.

Yes, using the R CMD INSTALL call in my first email.

See the above error message:
/usr/local/lib/R/site-library/rJava/libs/rJava.so
$ ls -al /usr/local/lib/R/site-library/rJava/libs/rJava.so
-rwxr-xr-x 1 egonw staff 128075 2006-10-22

Yes.
The patch to apply to the source to get it compiled and installed now looks
