clang-3.1 @3.1_1 +analyzer Scripts use /opt/local/bin/perl5, but dependency is missing/wrong

[naesten@…]

Symptoms

In particular, we have:

iMac:clang user$ port contents clang-3.1 | tail -n +2 | xargs grep '#!.*perl'
Binary file /opt/local/libexec/llvm-3.1/bin/clang matches
Binary file /opt/local/libexec/llvm-3.1/bin/clang++ matches
/opt/local/libexec/llvm-3.1/bin/scan-build:#!/opt/local/bin/perl5
/opt/local/libexec/llvm-3.1/libexec/scan-build/c++-analyzer:#!/opt/local/bin/perl5
/opt/local/libexec/llvm-3.1/libexec/scan-build/ccc-analyzer:#!/opt/local/bin/perl5
/opt/local/libexec/llvm-3.1/libexec/scan-build/scan-build:#!/opt/local/bin/perl5

and:

iMac:clang user$ port info --depends clang-3.1
depends_build: 
depends_run: port:clang_select, port:ld64, bin:python:python26, bin:perl:perl5
depends_fetch: 
depends_lib: port:llvm-3.1, port:libffi
depends_extract: 

Which, on my system, results in the likes of this:

iMac:clang user$ /opt/local/libexec/llvm-3.1/bin/scan-build 
/opt/local/libexec/llvm-3.1/bin/scan-build: /opt/local/bin/perl5: bad interpreter: No such file or directory

Analysis

Since bin: dependencies refer to files anywhere along the a search path, they are not a terribly good fit for shabang lines that refer to binaries using absolute paths (rather than using /usr/bin/env to find them).

Hopefully, these scripts are simple enough that they could simply have their shabang lines changed to #!/usr/bin/perl; it would be a bit of a pain to have to install perl from macports just for them...
