While trying to put the macport for 0.6.1 together, I noticed that the
install failed.

Tracked it down to the fact that --parrot_is_shared=0 seems to be
generating a parrot that relies on a shared lib.

This is happening for me on osx/86 (but the build works because it's
finding the blib/lib version: once you install it, this fails because
then it can't find the lib.), and on linux/x86 on feather (the build
fails because miniparrot requires the shared library and can't find
it, stopping the build immediately).

This worked as recently as 0.5.2 (the last macport)

I haven't touched this since it was initially reported.

Coke: Is this still problematic?

Verified, this still fails[1] as of r36803. This, combined with TT #344,
blocks creation of a functioning macport.
[1] Generates a parrot that depends on libparrot.dylib

That's because Configure.pl doesn't allow you any way to override the
hints file. What I had in mind was a more primitive, ruthless editing of
the darwin hints file, something like this (totally untested)

What I have in mind is a more general conf approach.

1. Disallow $conf->data->set('key') at all if $conf->options->get('key')
exists, only allow $conf->data->add('key').
Users try to fix the wrong hints options, and this is not enforced.
Only some keys are cooperative, most not.

2. Allow all keys to be given at the Configure.pl cmdline as in perl5.
Append (Apply after hints), Undefine and Define.

-Dcc_debug=-g3, -Ulibparrot_static, -Alinkflags=-Wl,--stack,8388608

perl5 Configure:
-D : define symbol to have some value:
-D symbol symbol gets the value 'define'
-D symbol=value symbol gets the value 'value'
common used examples (see INSTALL for more info):
-Duse64bitint use 64bit integers
-Duse64bitall use 64bit integers and pointers
-DEBUGGING=none DEBUGGING options
-Dcc=gcc choose your compiler
-Dprefix=/opt/perl5 choose your destination
-U : undefine symbol:
-U symbol symbol gets the value 'undef'
-U symbol= symbol gets completely empty
e.g.: -Uversiononly
-A : manipulate symbol after the platform specific hints have been
applied:
-A append:symbol=value append value to symbol
-A symbol=value like append:, but with a separating space
-A define:symbol=value define symbol to have value
-A clear:symbol define symbol to be ''
-A define:symbol define symbol to be 'define'
-A eval:symbol=value define symbol to be eval of value
-A prepend:symbol=value prepend value to symbol
-A undef:symbol define symbol to be 'undef'
-A undef:symbol= define symbol to be ''
e.g.: -A prepend:libswanted='cl pthread '
-A ccflags=-DSOME_MACRO

This was intended as a quick hack to try to get something --- anything --
working prior to the 0.9.1 release.

I'm not sure what, exactly, you mean here, but that's ok.

See the related discussion in [perl #42412]. (I've updated RT with the
relevant link.)

In any case, I won't have any time to do anything parrot-related for at
least the next several weeks, so I'm afraid I can't be of further help
here.
