installing Sly on older version of Mac OS X

[Roger A. PURVES]

to the experts on Guile:

I am trying to get Sly working under Mac OS X Snow Leopard, and am
fairly ignorant of the command line. I did get Guile running. That is,
I can type "Guile" at the bash shell prompt and Gnu Guile 2.0.11
comes up (and works fine). To get to SIy, I followed the instructions
(after installing wget on Mac OS X using brew(*)):
……………………………………………………………………………..
wget https://files.dthompson.us/sly/sly-0.1.tar.gz
tar xf sly-0.1.tar.gz
cd sly-0.1
./configure
make
make install
………………………………………………………………………………

given at the site

https://dthompson.us/projects/sly.html

but after issuing ./configure, I got the
response:
………………………………………………………………………............
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... build-aux/install-sh -c -d
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables... yes
checking whether make supports nested variables... (cached) yes
checking for guile... /usr/local/bin/guile
checking for guile... (cached) /usr/local/bin/guile
checking for Guile version >= 2.0.11... 2.0.11
checking for guild... /usr/local/bin/guild
checking for guile-config... /usr/local/bin/guile-config
checking if (sdl sdl) is available... no
configure: error: required guile module not found: (sdl sdl)
…………………………………………………………………………………

Likely foolishly, I tried Make after that. The response:

make: *** No targets specified and no makefile found.  Stop.

I obeyed. Then did some google searching which led to me believe that
I simply do not have the background to proceed further.

Can a non-technical person get to Sly from here (in Mac OS X 10.6)?

Thank you for reading this far.

program.)
