Hello,

Is it possible to use Piston to manage a Mephisto (or any other app)  
installation while still using svn:externals to manage vendor/rails? I  
do not  
want to commit an entire copy of Rails to my repository just to use  
Piston to  
manage Mephisto – I have made no local changes to Rails, only to  
Mephisto.  
Though it appears simple enough, my problem with this configuration is  
that  
when running “piston update”, I receive the following notice:

Skipping ‘.’: pending updates – run “svn update .”  
X vendor/rails

Performing status on external item at ‘vendor/rails’

Even after running “svn update”, I receive the above notice. Is it  
possible to  
continue using svn:externals to manage vendor/rails while using Piston  
to  
manage and update the root Mephisto directory?

Thanks,

Jeff
