Please, please, do not reinvent the wheel here! Most of the Linux 
distros has solved this in a very elegant way. It might not be possible 
to compile those packages directly on Solaris because of GPL issues, but 
at least their ideas can be leveraged.

Another option is to look to different, but yet similar dependency 
management solutions like Apache Maven which could provide a build system.
