I’m installing the R language and its sf package through a flake, if I do nix develop which R returns a path in the nix store (I have R installed globally too, on regular Linux).
The curious thing is that I tried this flake on two other machines, and it worked.
On the affected machine I also tried to reinstall nix (via the determinate systems installer). Is this a flaw in the flake.nix or is there an issue with my setup?
As soon as try to load the sf library, I get the error
> library(sf)
Error: package or namespace load failed for 'sf' in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/michael/R/x86_64-pc-linux-gnu-library/4.3/units/libs/units.so':
libudunits2.so.0: cannot open shared object file: No such file or directory
As well as several warnings after starting R, before the error:
During startup - Warning messages:

2: Setting LC_COLLATE failed, using "C"
3: Setting LC_TIME failed, using "C"
