As mentioned in a previous message, I tried to compile things with --- 
static, but that didn't do anything.
Providing a symbolic link to the dylib that is called doesn't do the  
trick, the error message stays the same.

Immanuel Litzroth wrote on the list about a way to nudge guile into  
using the .dylib extenstion instead of the .so when searching for  
libraries.
To me this seems the most promising, especially with the future in mind.
