where is the lock file

[Lenore Horner]

I accidentally hit cmd-Q when I wanted cmd-W and killed terminal in  
the middle of compiling qt4-mac.  When I tried to start again I got

Waiting for lock on /opt/local/var/macports/build/ 
_opt_local_var_macports_sources_rsync 
.macports.org_release_ports_aqua_qt4-mac/work/.macports.qt4-mac.state

I went to /opt/local/var/macports/build/ 
_opt_local_var_macports_sources_rsync 
.macports.org_release_ports_aqua_qt4-mac/work/ but there is no lock  
file there.  Where is it?

Thanks,
