5010,ghc-asm has a poor shebang,mcandre,igloo,"During a cabal install of Snap and its dependency bytestring-mmap, ghc-asm complained that it couldn't run.

}}}

Upon further investigation, it was determined that ghc-asm wouldn't run due to its shebang.

{{{
$ less /Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm

#!/opt/local/bin/perl
$TARGETPLATFORM  = ""i386-apple-darwin"";
}}}

I installed !MacPorts in ~/macports, not /opt/local. When GHC was installed, it should have used the shebang

{{{
#!/usr/bin/env perl
}}}

which does not depend on !MacPorts being installed in /opt/local, or for that matter !MacPorts being installed at all.
