 The [http://build.macports.org/builders/buildports-snowleopard-
 x86_64/builds/6021/steps/compile/logs/stdio buildbot reports] that
 clang-2.9, clang-3.0 and clang-3.1 fail activation because of the presence
 of unregistered files /opt/local/libexec/llvm-*/bin/ld:

 clang-2.9:

 `Error: Target org.macports.activate returned: Image error:
 /opt/local/libexec/llvm-2.9/bin/ld already exists and does not belong to a
 registered port.  Unable to activate port clang-2.9. Use 'port -f activate
 clang-2.9' to force the activation.`

 clang-3.0:

 `Error: Target org.macports.activate returned: Image error:
 /opt/local/libexec/llvm-3.0/bin/ld already exists and does not belong to a
 registered port.  Unable to activate port clang-3.0. Use 'port -f activate
 clang-3.0' to force the activation.`

 clang-3.1:

 `Error: Target org.macports.activate returned: Image error:
 /opt/local/libexec/llvm-3.1/bin/ld already exists and does not belong to a
 registered port.  Unable to activate port clang-3.1. Use 'port -f activate
 clang-3.1' to force the activation.`

 I have {clang,llvm}-{2.9,3.0} installed on my system (not yet updated to
 the very latest version), and /opt/local/libexec/llvm-*/bin/ld does not
 exist on my system. Not sure what caused these files to get installed on
 the buildbot but not on my system. But it sounds like maybe an older
 version of the ports inadvertently installed these files directly into
 ${prefix} bypassing ${destroot}. It would probably be best for the clang
 ports need to clean up this situation. See the bottom of r38613 for an
 example of how this can be done.
