Not a risk, it is virtually guaranteed. If any port re-installs qt3,
any subsequent port that requires qt* will use qt3. We all ready have
knobs for:

WANT_OPENLDAP_BASE=24
WITH_OPENSSL_PORT=yes
WITH_BDB_VER=5
BOGOFILTER_BDB_VER=5
PYTHON3_DEFAULT_VERSION=python3.3
WITH_VIM_OPTIONS="YES"
RUBY_DEFAULT_VER=1.9

 ... etcetera.

We need a flag for:

DON'T_EVEN_THINK_ABOUT_USING_QT3= yes
