I would write a little script. There are examples how to send to
netreceive written in perl and python in the CVS or on pure-data.info,
it's really simple.

You could also use the pdsend utility, however doing it in Python is
more flexible IMO, especially as you also need to append a ";" after
each line to send. 

You could direct the apache log output to a FIFO pseudofile created
with "mkfifo /path/to/fifo" on Linux, then read from there, or do a
"tail"-clone in Python or use bash or whatever.
