www/serf failing with missing db4

[Martin Husemann <martin%duskware.de@localhost>]

Hey folks,

on netbsd-8, the build of www/serf fails for me with:

gcc -o libserf-1.so.1.3.0 -L/usr/pkg/lib -Wl,-R/usr/pkg/lib -L/usr/lib -Wl,-R/usr/lib -pthread -shared -Wl,-Bsymbolic -Wl,-soname=libserf-1.so.1 -Wl,-R/usr/pkg/lib -Wl,-R/usr/pkg/lib -Wl,-R:/usr/pkg/lib -Wl,-R:/usr/pkg -Wl,-R:/usr/pkg/lib/lib context.os incoming.os outgoing.os ssltunnel.os buckets/aggregate_buckets.os buckets/allocator.os buckets/barrier_buckets.os buckets/buckets.os buckets/bwtp_buckets.os buckets/chunk_buckets.os buckets/dechunk_buckets.os buckets/deflate_buckets.os buckets/file_buckets.os buckets/headers_buckets.os buckets/iovec_buckets.os buckets/limit_buckets.os buckets/mmap_buckets.os buckets/request_buckets.os buckets/response_body_buckets.os buckets/response_buckets.os buckets/simple_buckets.os buckets/socket_buckets.os buckets/ssl_buckets.os auth/auth.os auth/auth_basic.os auth/auth_digest.os auth/auth_spnego.os auth/auth_spnego_gss.os auth/auth_spnego_sspi.os -L/usr/pkg/lib -L/usr/pkg -L/usr/pkg/lib/lib -lssl -lcrypto -lz -lapr-1 -lrt -lpthread -laprutil-1 -ldb4-4.8 -lexpat -lgssapi -lheimntlm -lkrb5 -lhx509 -lcom_err -lhcrypto -lasn1 -lwind -lheimbase -lroken -lcrypt
ld: cannot find -ldb4-4.8


... and I don't see how databases/db4 could ever come in here.
Any ideas?
