creating packages

[svs57]

I want create some perl packages.
I download sources and debian patches from package.debian.org
When I try to make package I got error because of busybox find:
----------------------------------------------------------
Nokia-N810-51-3:~/xmltv/libterm-readkey-perl-2.30.orig# make -f debian/rules binary-arch
dh_testdir
dh_testroot
dh_clean -k
BusyBox v1.6.1 (2007-09-27 18:08:59 EEST) multi-call binary

Usage: find [PATH...] [EXPRESSION]

dh_clean: command returned error code
----------------------------------------------------------
Do anybody know where can I get version of busybox which is compatible with debian tools?
I have rootfs on SD and have space to install real GNU tools
But I don't know how...
