Please post config.log.
Created attachment 457122 [details] config.log from icedtea-3.2.0 with kerberos USE-Flag
The only pkg-config file that heimdal 1.5.3 installs is heimdal-gssapi.pc. I see that 7.0.1 (masked) has krb5.pc.in but I'm not 100% sure whether it normally installs krb5.pc from this. Andrew, is icedtea supposed to support heimdal? Note that most distros allow it to be installed simultaneously with mit-krb5 but on Gentoo, they block each other.
With heimdal 7.1 find icedtea 3.2.0 the Kerberos-Implementation and build normal.
