Indeed.  Fixed in 1327ec822fa6dd396e979efd8d4e1f7479f1d5b3.

Hello all,
I have been playing around with the 'guix import' tools to
see how easily I can get some package definitions. In the process of
trying to package https://github.com/Spotifyd/spotifyd with 'guix import
crate spotifyd -r' I found that one of the nested dependencies,
libpulse-sys <at> 0.0.0 did not work with the automatic importer because it
does not have a license in its crate
https://crates.io/crates/libpulse-sys/0.0.0.

Obviously it would be ideal to get whoever is using this out-of-date
library in their package to update their dependencies so this is
entirely avoided, but short of that has there ever been discussion on
how to handle 'license-less' packages? I haven't seen any in my short
time lurking on this list. It seems to be a rigid requirement for the
crate importer.
