Hi Evan,

Evan Straw <evan.straw99@gmail.com> skribis:

> I am attempting to load "/usr/lib/x86_64-linux-gnu/libcurl.so.4" since

That cannot work: this libcurl.so is linked against a different libc
(among other things) than the =E2=80=98sbcl=E2=80=99 program from Guix, so =
trying to
load it in a running Guix =E2=80=98sbcl=E2=80=99 is bound to fail.

What would work instead is loading Guix=E2=80=99 libcurl.so.  I suppose you
could do that by removing /usr/lib from =E2=80=98*foreign-library-directori=
es*=E2=80=99.

HTH!

Ludo=E2=80=99.
