Using the native Kerberos implementation on Solaris is not possible.

>Fix:
Header files for native Kerberos on Solaris 10 are found in

/usr/include/kerberosv5/

Adding a check in security/mit-krb5/builtin.mk for

BUILTIN_FIND_FILES.H_MIT_KRB5=         /usr/include/kerberosv5/krb5.h

seems sufficient, so that setting

KRB5_DEFAULT =               mit-krb5
PREFER_NATIVE =              mit-krb5

lets pkgsrc use the native implementation. Tested (in the sense that 
security/p5-GSSAPI builds against it) on MACHINE_PLATFORM=SunOS-5.10-i386.
