Build image wireless-regdb

I'm trying to use ' Image Builder' but it fails with error
'opkg_install_cmd: Cannot install package wireless-regdb'

I couldn't find the appropriate .ipk file, so I copied this one:
wireless-regdb_2017-10-20-4343d359_arm_cortex-a5_neon-vfpv4.ipk
to packages/ and renamed to *_mipsel_74kc.ipk
(assuming its just some config file with regulatory country options)
it still didnt work.
?

thx.

I recall build problems in the last day with that specific package due to a Python module not being available. This may have impacted the project’s builders so it may not be on the repo right now

Edit:

I see.
when shall wireless-regdb be built for mipsel_74kc?
thanks.
