Exactly when? I can still reproduce.

If you're referring to clang -exp runs see last comment in ports/159117.
Leaving aside the issue of portmgr@ embracing false positives

# notice 'cc' is used with no clang-specific warnings (then 'cc' is 'gcc')
# notice '-O2 -pipe -fno-strict-aliasing' are not actually used

So, try USE_GCC=4.6+ and see if the log contains gcc46 or set CC yourself
but place a few traps to prevent build from lying (see quote below).

Note, assignment on command line has higher precedence than in Makefile.
For example, the following

  $ make CC=gcc46

overrides CC=cc in lib/viqr/Makefile but fails to work when CC is set
via environment, make.conf or bsd.gcc.mk (USE_GCC).
