Hola Loïc,

Good suggestions!  It appears that I can't remove any file using fakeroot:

   p@satan$ touch blah; chmod ugo+rw blah

   p@satan$ ll blah 
   -rw-rw-rw-  1 p p 0 2004-12-12 11:04 blah

   p@satan$ rm -rf blah 

   p@satan$ ll blah
   ls: blah: No such file or directory

   p@satan$ touch blah; chmod ugo+rw blah

   p@satan$ fakeroot rm -rf blah 
   rm: cannot remove `blah'


However, "strace -ff" was telling.  The second I saw "preload libtrash.so", I
knew exactly what was happening.

I use libtrash, which moves files to ~/Trash whenever a call to unlink is
made.  The child process spawned by fakeroot tried to move blah to
/root/Trash.

However, I never use root for anything, so I don't preload the libtrash
library for the root user.  I'm normally really careful with that account, so
I don't need libtrash for it.  Well, not only that, but even if /root/Trash
did exist, I don't think I'd be able to write to it anyhow, even with
fakeroot (if I understand fakeroot correctly).

Anyway, moving blah to /root/Trash failed, so the child process exited
"unexpectedly".

Moral to the story: fakeroot and libtrash don't mix well.

The package appears to be building correctly.  Now I just sit back and wait
to see if the rest continues.

Thank you for the strace suggestion; it definitely was the perfect
suggestion!

Pete
