Deleting emulators/compat80

I've noticed that when I try to delete the emulators/compat80 package
it complains a lot about trying to remove files from a read-only file
system:

 # pkg_delete compat80
 compat80-8.0: removing /lib/libpcap.so.6
 rm: /lib/libpcap.so.6: Read-only file system
 compat80-8.0: removing /usr/X11R7/lib/libXfontcache.so
 rm: /usr/X11R7/lib/libXfontcache.so: Read-only file system
 compat80-8.0: removing /usr/X11R7/lib/libXfontcache.so.2
 rm: /usr/X11R7/lib/libXfontcache.so.2: Read-only file system
 ...

Is this normal?  Shouldn't it be removing files from somewhere in
/usr/pkgsrc/... ?
