[plt-scheme] errortrace

Hi,

I have been using setup-plt to add better errortrace support to a module 
that I have development.  I have noticed that when I execute setup-plt 
it updates other modules that it uses.  Consider the following:

# setup-plt --mode errortrace -l apv-utilities

setup-plt: Setup version is 299.30
setup-plt: PLT home directory is /usr/local/plt/
setup-plt: Collection paths are
setup-plt:   /usr/local/plt/collects/
setup-plt: Compiling .zos used by APV Utilities
setup-plt:   in /usr/local/plt/collects/apv-utilities/
setup-plt:   in /usr/local/plt/collects/scheme-pg/
setup-plt:   in /usr/local/plt/collects/errortrace/
setup-plt:   in /usr/local/plt/collects/srfi/
setup-plt:   in /usr/local/plt/collects/srfi/13/
setup-plt:   in /usr/local/plt/collects/srfi/8/
setup-plt:   in /usr/local/plt/collects/srfi/14/
setup-plt:   in /usr/local/plt/collects/mzlib/
setup-plt:   in /usr/local/plt/collects/syntax/
setup-plt:   in /usr/local/plt/collects/mzlib/private/
setup-plt:   in /usr/local/plt/collects/setup/
setup-plt:   in /usr/local/plt/collects/srfi/1/
setup-plt:   in /usr/local/plt/collects/srfi/19/
setup-plt:   in /usr/local/plt/collects/srfi/29/
setup-plt: Updating /usr/local/plt/collects/info-domain/compiled/cache.ss
setup-plt: Done setting up

Is it possible to instruct setup-plt to only update errortrace support 
on my module and not any module used by it ?

Thanks,
Arend
