Bundler is a packaging tool that typically works at the source tree
level. Its approach is to pull all dependencies in. With Guix we don't
have much use for it. Better to package gems in Guix and benefit from
a true reproducible and dependable deployment system that *includes*
underlying dependencies, such as libxml and all that.

Sometimes it is useful to try gems.  I did write up in the past how I
mix Guix packages with Ruby gems.  Using bundler is just another
layer. See

Not much love for bundler therefore ;)
