Hi,

IPython is a Python REPL and there is no direct dependencies on bluez or
jack.  Why does it need unrelated tools as some Bluetooth or JACK audio?

--8<---------------cut here---------------start------------->8---
$ guix size python-ipython | grep -E '(jack|bluez)'
/gnu/store/kbvyzkxrpf8w9v64jvjkr12hcailhflx-bluez-5.66             192.8     4.3   0.2%
/gnu/store/7bhggk7fzvgjvgi9ykphgg21gwlfgx4k-jack-0.125.0            90.8     1.3   0.1%

Well, any idea why bluez or jack are in the picture?

--8<---------------cut here---------------start------------->8---
$ for p in $(guix show python-ipython | recsel -C -P dependencies); do guix size $p ;done | grep -E '(bluez|jack)'
… nothing!

Last, the chain of dependencies looks like:

--8<---------------cut here---------------start------------->8---
$ guix graph --path python-ipython bluez
python-ipython <at> 8.5.0
python-matplotlib <at> 3.5.2
python-wxpython <at> 4.2.0
wxwidgets <at> 3.2.2.1
sdl2 <at> 2.26.2
pulseaudio <at> 16.1
bluez <at> 5.66

$ guix graph --path python-ipython jack
