  hm.  this was interesting.  I'm doing:

DEPEND="virtual/x11
            tk? ( dev-lang/tk )"

src_compile() {

        local myopts

        if [ "`use tk`" ]
        then
                myopts="--with-tk"
        fi

        ./configure \
                --host=${CHOST} \
                --prefix=/usr \
                --infodir=/usr/share/info \
                --mandir=/usr/share/man \
                --sysconfdir=/etc \
                --localstatedir=/var \
                ${myopts} || die "./configure failed"
        
        make all || die
}

  and for testing I tried the command line:

USE="-tk" emerge scilab

  now, the dependency-check comes out as it should, portage doesn't
  start to grab TCL/TK.  _but_ the "`use tk`" doesn't seem to notice
  the USE="-tk" statement.  I have "tk" listed as a USE-flag in
  /etc/make.conf but I would _really_ expect Portage to ignore that
  when I explicitly say that I don't want tk right now on the command
  line.  hopefully I'm doing something very stupid, can someone please
  tell me how to deal with this?

  (sent to both gentoo-user and gentoo-dev, with reply set to
  gentoo-dev)
