${corelist:Depends} is computed in debian/rules:
CORELIST = $(shell apt-cache policy libmodule-corelist-perl | awk
'/Candidate/ {sub(/-[^-]+$$/,"",$$2); print $$2;}')
Yes, of course, that's the point where it's failing ...
Looks like CORELIST variable can be empty in the buildd.
... because of the "fails to open /var/cache/apt/pkgcache.bin". Now the
interesting question is _why_ this happens.
We need to re-think how this dependency is computed.
Hm, yeah, as Lucas has proven that might be too fragile ...
You really shouldn't use apt-cache. First of all, you don't build-depend
on apt explicitly (only indirectly, via libapt-pkg-perl). Secondly, apt
cache is not guaranteed to contain anything interesting: a user is free
to remove all entries from his sources.lists.
Any ideas on how to get the version without using apt-cache?
Build-depend on libmodule-corelist-perl and then use "dpkg-query -W".
