Strange... Here's what I get:

$ make distclean
$ ls -lh server/drivers/hd44780.so
ls: server/drivers/hd44780.so: No such file or directory
$ ./configure --enable-drivers=3Dhd44780
$ make
$ ls -lh server/drivers/hd44780.so
-rwxr-xr-x 1 gfk gfk 47K May 2 19:55 server/drivers/hd44780.so

Could you provide a copy of your make output:
make > make.log 2>&1

Seems like a speed or interference problem.

If you have a super GHz computer it may happen that the signal timing=20
generated by LCDd is too fast. Adjust DELAYMULT in the source file to a=20=

bigger value. Parallel port wirings usually don't permit to read back=20
the busy flag of the controller chip, so timing must be adjust so that=20=

the controller never is busy.

Try that and tell us if it works for you,
