is it safe to disable B::C with distroprefs?

Hello folks,

I generating a new version of CPAN Smoker for OpenBSD 6.7 and was
surprise by getting 1.2GB of storage on build_dir during the setup of
B::C. Since I'm using mfs (memory based filesystem) to improve things a
bit, the whole setup process goes down because the mfs is not large
enough to hold B::C setup.

Is it safe to disable it with distroprefs? I'm installing a lot of
modules as dependencies, but not sure why it is being included. Checking
here:

https://cpants.cpanauthors.org/release/RURBAN/B-C-1.57/used_by

Makes me wonder if I really need it.

Best regards,
Alceu
