 Priority:  Normal             |   Milestone:                                       
Component:  ports              |     Version:  2.1.1                                
 Keywords:                     |        Port:  clang-3.1

 == 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...
