>Description:
Building dovecot2 on FreeBSD 9.2 using security/heimdal port results in configure returning 

/usr/bin/ld: cannot find -lgssapi_krb5

which is correct, because libgssapi_krb5 isn't built by the security/heimdal port.
The security/heimdal port builds libgssapi to contain the calls that lower versions of heimdal use in libgssapi_krb5.




>How-To-Repeat:
rm /usr/lib/libgssap* 
# In my case I don't build these, via src.conf WITHOUT_KERBEROS
cd /usr/ports/security/heimdal && make install package
cd /usr/ports/mail/dovecot2 && make install package

>Fix:
.if defined(HEIMDAL_HOME)
BUILD_DEPENDS+=  ${HEIMDAL_HOME}/lib/libgssapi.so:${PORTSDIR}/security/heimdal
RUN_DEPENDS+=  ${HEIMDAL_HOME}/lib/libgssapi.so:${PORTSDIR}/security/heimdal
.else
LDFLAGS+=       -lgssapi_krb5
.endif

or for a minimal solution

.if !defined(HEIMDAL_HOME)
LDFLAGS+=       -lgssapi_krb5
.endif

It is common practice to use HEIMDAL_HOME as both the trigger for recognition of use of the security/heimdal port as well as the location of the libs and headers.
