I already had libgc from Guix, and indeed it was the one picked up by
Guile.  The problem seems to be limited to guile-readline.

I guess the problem might be related to an "-rpath /usr/lib" that ends
up in 'relink_command' in guile-readline/libguilereadline-v-18.la:

--8<---------------cut here---------------start------------->8---
# Directory that this library needs to be installed in:
libdir='/usr/lib'
relink_command="(cd /home/mhw/guile/guile-readline; /bin/bash 
/home/mhw/guile/libtool  --silent --tag CC --mode=relink gcc -Wall 
-Wmissing-prototypes -Wdeclaration-after-statement -Wpointer-arith 
-Wswitch-enum -fno-strict-aliasing 
-I/nix/store/a9j9bl7m73rhlal9z83z3wbl9m17di4i-libgc-7.4.0/include -g -O2 
-version-info 18:0:0 -export-dynamic -no-undefined -o libguilereadline-v-18.la 
-rpath /usr/lib readline.lo -lreadline -lncurses ../libguile/libguile-2.0.la 
../lib/libgnu.la -lcrypt -lm @inst_prefix_dir@)"
--8<---------------cut here---------------end--------------->8---

I'm not sure why libtool is putting that rpath in there, but here are
some possibly relevant lines from config.log:

--8<---------------cut here---------------start------------->8---
BDW_GC_LIBS='-L/nix/store/a9j9bl7m73rhlal9z83z3wbl9m17di4i-libgc-7.4.0/lib -lgc 
 '
GUILE_LIBS='  -lcrypt -lm '
INTL_MACOSX_LIBS=''
LIBFFI_LIBS='-L/nix/store/49535xllwsa3mwddjj1hny84l0p7c453-libffi-3.0.13/lib 
-lffi  '
PTHREAD_LIBS=''
READLINE_LIBS='-lreadline -lncurses '
--8<---------------cut here---------------end--------------->8---

All of the libraries listed above are in ~/.guix-profile/lib, but it
seems that only the ones that are found using 'pkg-config' end up with
corresponding -L arguments.

Also possibly relevant: I don't have LD_LIBRARY_PATH set.  Should I?

The only environment variables I have pointing to anything Guix-related
are the ones I listed in my previous email.  Am I missing anything?

   Thanks,
     Mark
