Hi!

Yea, for example consider the invocation `guix import pypi cart`.
Without this patch, this emits the following error message for me
on Alpine Linux Edge (a musl-based Linux distribution):

	guix import: error: no source release for pypi package cart 1.2.2

	hint: Backtrace:

	ERROR: In procedure dlopen:
	In procedure dlopen: file "libutil.so", message "libutil.so: cannot open shared object file: No such file or directory"

With this patch applied, I instead get:

	guix import: error: no source release for pypi package cart 1.2.2

	hint: This indicates that the package is available on PyPI, but only as a "wheel" containing
	binaries, not source.  To build it from source, refer to the upstream repository at
	`https://github.com/CybercentreCanada/cart'.

I assume the fallback code in syscall->procedure does not work correctly
then and the "correct fix" would be to fix this fallback code?

Greetings,
Sören
