#1 Compile errors on Mac OS X

Ironically, libipod 1.0 doesn't build on Mac OS X. After a fair number of
warnings, it grinds to a halt with errors compiling ipod.c:

ipod.c:41:24: error: sys/statfs.h: No such file or directory
ipod.c: In function 'ipod_disk_usage':
ipod.c:227: error: storage size of 's' isn't known

There is no statfs.h on OS X. I'm not sure what it's for; any idea how to
work around its absence?

I got past that error -- statfs is declared in sys/param.h and sys/mount.h on
OS X, so I changed the #include. (Not sure how to do that in a cross-platform
way.)

The next blocker is:
../libtool: line 2733: bundle: command not found

This error happens because the variable $EGREP isn't defined to anything
meaningful: line 88 reads
EGREP=""
Presumably it should instead be set to "/usr/bin/egrep". Apparently this file is
automatically generated, so I'll have to figure out where this is coming from...
