As announced in the UPDATING entry 20141123, the location of headers and installed libraries for the security/heimdal port changed.
The attached patch fixes both the detection of the installed library and the header/lib locations of the Makefile if the HEIMDAL_PORT option is selected.
Assign correctly to ftp/curl maintainer
Please consider to use USES=gssapi to fix this issue instead of using hard-coded pathnames for header files and libraries.
ftp/curl uses USE=gssapi since r382459. I've tested all GSSAPI_* options and it builds without error. Please update ports tree and report if it works for you.
