Hallo Hans-Christoph,

I'm glad those suggestions were a help.

I have no idea about "strip". I haven't used it, and I'm 95% sure it's
not a necessary step. Looking at the Mac man page alone doesn't make it
any clearer. However, from the Linux man page:

--strip-unneeded 
  Strip all symbols that are not needed for relocation processing.

and now from the start of strip(1) in darwin-land:

       strip no longer removes relocation entries under any  con-
       dition.   Instead,  it  updates  the  external  relocation
       entries (and indirect symbol table entries) to reflect the
       resulting symbol table.

...so it sounds like strip, as used here in Pd-land, is not terribly
useful, but further on in strip(1)-darwin:

       When strip is used with no options on an executable  file,
       it  checks  that  file  to see if it uses the dynamic link
       editor.  If it does, the effect of the  strip  command  is
       the  same as using the -u and -r options.

... so that sounds to me like you might like to _experiment_ with strip
using no options, and see if the default behaviour yields something
that's still usable. :)

Otherwise, if others know better about using strip, especially on Mac OS
X, please chime in. 

Cheers,
adam
