But should suffice to be

DEPEND="sys-devel/gcc[gcj]"
RDEPEND="${DEPEND}"

i.e. DEPEND not RDEPEND. The 6.4.x part is implicit by 7.x lacking the
gcj USE-flag. OTOH, in my ebuild I explicitly depend on 6.4.0 (but
only because I gcc-config'ed to gcc-7.2), so... If you have 6.4.0
selected, that explicit dep could be killed. It's just a matter of
'gcj' and 'gcjh' being in the path and found (and a matching gcc too).

And BTW, you can't change to java/icedtea, I've looked at the code,
it'd be a major rewrite, pdftk uses lots of gcj specific stuff.

I'll attach my whole diff to the original 2.02.ebuild.

HTH,
