I rejected ted's reply because 2MB of logs seemed excessive. Here's a
relevant bit of the log:

It suggests that krb5-config was used, but it only put -lkrb5 in
libs.
That's consistent with what I see on ubuntu trusty:

% krb5-config.heimdal --version
heimdal 1.6.99
% krb5-config.heimdal --libs
-L/usr/lib/x86_64-linux-gnu/heimdal -lkrb5

It apears to get the full set of libraries, you need to add --deps:

% krb5-config.heimdal --libs --deps
-L/usr/lib/x86_64-linux-gnu/heimdal -lkrb5 -lhx509 -lcom_err -lhcrypto
-lasn1 -lwind -lheimbase -lroken -lcrypt -pthread -lpthread -ldl -lresolv
-pthread -lpthread
