That seems like quite a few dependencies.
If you specify the dependecies correctly it should work.
ie:
Package 1 depends on acs-kernel
Package 2 depends on Package 1
Package 3 depends on Package 2
.
.
.
Package 15 depends on Package 14.
If you set it up this way, all package 15 depends on is package 14, and each package depends on the previous one being installed before it can be installed.
Will this work for you?
If not perhaps you can be a little more explicit in which packages you are using together. Are any of the 15 standard OpenACS packages?
