dlopen Objective-C runtime before fork(2)

[skaji]

It seems that #248 does not fix #246.
Actually I failed to execute cpm on macos 13.7.1 with /usr/bin/perl in github action (macos-13).

So we reverted to the previous fix #247.

Looks like the issue this was meant to address is still present?

Can you provide the whole output of cpm --version ?

[skaji]

And also can you provide

sw_vers
uname -m

?

Thank you.

perl version v5.34.1 (perl)

So, it seems that $^X is perl, not /usr/bin/perl.
This case was not anticipated.

@nathanweeks Can you try "patch-fatpack" branch?

curl -fsSL https://raw.githubusercontent.com/skaji/cpm/patch-fatpack/cpm > cpm
perl cpm --version
perl cpm install JSON

[nathanweeks]

That version works!
