#54226: "/opt/local/bin/as: assembler (/opt/local/bin/clang) not installed"

--------------------+---------------------
 I found a rogue /opt/local/bin/clang (symlink) that didn't belong to any
 port and I never did a `port select clang` so I removed the file because I
 also couldn't remember why I would have created it.

 I quickly found out:

 {{{
 > /opt/local/bin/as -q
 /opt/local/bin/as: assembler (/opt/local/bin/clang) not installed
 }}}

 That reeks of an error. AFAIK ports should not depend on the user having
 used port select, and port:cctools doesn't indicate that one should do a
 port select.

 What's more, after reinstalling the symlink (this time via `port select`):

 {{{
 > /opt/local/bin/as -v -q
 clang version 4.0.0 (tags/RELEASE_400/final)
 Target: x86_64-apple-darwin13.4.0

 }}}

 IOW, it would appear that the actual selected clang executable is
 hardcoded, presumably through a variant dependent patch. Maybe one
 location to patch got away?
