Re: Big picture of building & packaging

[dev]

The values of environment variables are identical in both versions:

LC_ALL: de
LANG: (null)
LC_CTYPE: (null)

However, I didn't realize until I investigated more (from lack of C programming 
experience), but how you looked up the symbol names is a really good direction.

When I build v0.21:

    U _rpl_setlocale (from libgettextlib-0.21.dylib)

When I build v0.21.1:

    U _libintl_setlocale (from libintl.8.dylib)
 
Though I am not sure of this reason.
