Description:        dblink compile with SSL missing libraries
Details: 

If I try to build dblink when PG is configured "--with-openssl", the build
of the contrib module dblink breaks as follows:

If I add, to the GCC command line, requests for libssl and libcrypto...
-lssl -lcrypto

e.g. - command line: 

pgdba(at)ydb1(dot)int(dot)libertyrms(dot)com:/opt/rg/data_dba/build-farm/HEAD/pgsql.741430/
contrib/dblink $ /opt/prod/gcc-4.1.1/bin/gcc -O2 -Wall -Wmissing-prototypes

-lpthread -lpthreads -lssl -lcrypto  -Wl,-bI:../../src/backend/postgres.imp


This builds fine without further complaint.
