I think this should sound familiar:

Error in getopt command line: Non-static method PEAR::isError() 
should not be called statically, assuming $this from incompatible 
context

Problem is that my PEAR installation resides in /opt/local/lib/php 
and that, while the PlufErrorHandler tries to ignore PEAR warnings 
and errors already, it fails to do that properly for violations 
coming from command line parsing.

The reason is that Pluf::start($what['conf']) is called many lines 
later in migrate.php and only this sets 'pear_path', so the error 
handler still assumes the default '/usr/share/php'.

I think all this boils down to the fact that Pluf's error handler is 
set as soon as Pluf.php is required (line 396 of Pluf.php) and that 
Pluf.php is require'd too early in migrate.php. I'll post a patch 
for this in a few.
