When splitting off the wrap and the crypto modules into own packages I
put them into recommends to make sure they are installed.

proftpd-dfsg (1.3.7a-2) unstable; urgency=medium

   [ Hilmar Preusse ]
   * Move modules depending on libsodium & libwrap0 into own packages.
     New packages are recommended.

Francesco later decided to put them into Suggests:

proftpd-dfsg (1.3.7a+dfsg-3) unstable; urgency=medium

   * Moved -mod-wrap and -mod-crypto among Suggests, thanks to changes
to default
     template for modules.conf.

So, you probably have a custom modules.conf and refused to use the one
from the package maintainers. So solution could be: either install these
packages or use the modules.conf from the package. Please send the
output of

apt install proftpd-core proftpd-basic proftpd-mod-crypto proftpd-mod-wrap

I'm wondering why this does not work: all packages should be unpacked
before the proftpd-core is configured, so all files needed to configure
proftpd-core should be available.
