Hi,

I was adding guile-ncurses to homebrew-guile and realized there might be an issue in the documentation.

According to this:

https://www.gnu.org/software/guile/manual/html_node/Modules-and-Extensions.html

the extensions directory is /usr/lib/guile/3.0/ (or /usr/local/lib/guile/3.0/m depending on your libdir). This is the directory where guile-ncurses installs libguile-ncurses library. 

However, I then saw that guile-readline was installed in /usr/local/lib/guile/3.0/extensions. I initially thought this was a Homebrew specific location. I looked at the Formula but there's nothing specific to Homebrew there.

Then, I looked at guile and found this:

http://git.savannah.gnu.org/cgit/guile.git/tree/libguile/Makefile.am#n772

which indicates the extensions path is really /usr/lib/guile/3.0/extensions.

I patched guile-ncurses with this and it works fine now on macOS.

In case this is correct, I'm including a patch to fix the manual.

Best,

Aleix
