thanks a lot for helping me...

in the ebuild i've exported the following variable:
ALT_BOOTDIR="${WORKDIR}/${PN}/bootstrap/jdk1.6.0"
because in the Makefile.am there is:
ICEDTEA_ENV = \
        "LANG=C" \
        "PATH=/usr/bin:/bin:/usr/sbin:/sbin" \
        "ALT_BOOTDIR=$(abs_top_srcdir)/bootstrap/jdk1.6.0" \

and here where it points:
# ls -l jdk1.6.0
lrwxrwxrwx 1 root root 3 2007-09-17 03:47 jdk1.6.0 -> ecj

and where it points:
jdk1.6.0/bin/java -> /usr/i686-pc-linux-gnu/gcc-bin/4.1.2/gij


here my other config:
# gcj-config -l
gcj-4.1.1
gcj-4.1.2
gcj-4.2.0_alpha20070131
gcj-4.3.0_alpha20070824 *

and:
# java-config -L
The following VMs are available for generation-2:
1)      GCJ 4.1.1 [gcj-jdk-4.1]
*)      GCJ 4.3.0_alpha20070824 [gcj-jdk-4.3]

and(in the ebuild):
        econf \
                --with-libgcj-jar=/usr/lib/gcj-4.3.0_alpha20070824/share/java/libgcj-4.3.0-alpha20070824.jar
\
                --with-ecj=/usr/bin/ecj-3.3 \
                --with-ecj-jar=/usr/share/eclipse-ecj-3.3/lib/ecj.jar \
                --with-xalan2-jar=/usr/share/xalan/lib/xalan.jar \
                --with-xalan2-serializer-jar=/usr/share/xalan-serializer/lib/serializer.jar
\
                --with-xerces2-jar=/usr/share/xerces-2/lib/xercesImpl.jar
|| die "econf failled"

econf is the equivalent of ./configure
and for building manualy i've passed the same --with
