     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.2.1
 Keywords:             |       Port:
-----------------------+--------------------------------
 /usr/bin/llvm-gcc-4.2 is adopted as a default c compiler for mpicc-mp in
 this port with default variants "+gcc48" even if the compiler does not
 exist. This may happens if Xcode 5 is cleanly installed since Xcode 5 does
 not include the compiler.

 As a consequence,  although installation of this port successfully
 finished, an error, "/opt/local/bin/mpicc-mp: line 290: /usr/bin/llvm-
 gcc-4.2: No such file or directory", always occurs if mpicc-mp is used.
 I experienced this error on a combination of OS X 10.8.5, Xcode 5.0.2.
 Xcode 5 was cleanly installed, not upgraded from Xcode 4.

 This error does not occur if Xcode 5 is upgraded from Xcode 4. In this
 case, it seems that /usr/bin/llvm-gcc-4.2 is still existing and usable. I
 checked it on another computer. Its combination of the versions of OS X
 and Xcode is the same with the system in which the error occurs. In this
 system, Xcode 5 was upgraded from Xcode 4.

 Additionally, if a variant "+gcc47", the c compiler is changed to
 /usr/bin/clang.

 Thank you.
