[Module-build-general] Understanding $Config{startperl} in MacPerl

[Ken W. <ke...@ma...>]

Hi,

I see that in MacPerl (not perl for OS X), $Config{startperl} is set to

     "Perl -Sx \"{0}\" {\"Parameters\"}; Exit {Status}\n#!perl"

in Config.pm .  I'm not sure what that extra stuff is before the 
shebang, but when I run a script that contains that (using 
MacPerl 5.6.1), I just get a perl syntax error.  When I remove 
it, all is well.

Can anyone enlighten about what that first line is for?

Schwern and I have been working on getting Module::Build to 
support MacOS natively, because (1) then MacOS won't have to use 
different module-building procedures from the rest of the world, 
and (2) it's a good cross-platform proving ground since it's so 
different from Unix.
