My impression was that Guile had some compatibility header in case readline 
isn’t installed. The missing names referred to several files, whereas in Guile, 
there was only one.

On OS X, readline isn’t installed by default, which probably was the reason. 
The same with pkg-config:

I have one in /opt/ from MacPorts, but packages in /usr/local/ may not read it. 
It may be that case with GC. So one has to install pkg-config in /usr/local/. 
Then another problem is that the MacPorts installer patches ~/.profile, add 
/opt first in the searchpath. So one has to remember setting that correct, too.

The Guile INSTALL mentions pkg-config, but only after GC, though it must be 
installed before it, and does not say where to get it. It is a recursive 
package, so one has to get around that.
