As far as I can see, there is no direct support for that on Solaris,
yet, although the infrastructure is in place and is used for
Darwin/MacOS X which also provides native Java.

Pkgsrc can use certain native software from the host OS instead of a
pkgsrc package if there is a file "builtin.mk" in the package directory
and builtin.mk is able to recognise this native software. As an example,
we use this mechanism to use native zlib instead of devel/zlib, if
available.

For Java, the files lang/sun-j(dk|re)*/builtin.mk need to be taught to 
recognise the respective Java version.
Then you would be able to set USE_JAVA2=1.5 in your mk.conf and pkgsrc
would require sun-jdk15 and if builtin.mk saw there already was Java 1.5
available on your Solaris system, it would set appropriate variables for
pkgsrc to use the native Java version.

You could try to adapt the existing builtin.mk files to support Solaris.
