Thanks for the report and sorry about the problem.
I'm OK with changing the error to a warning.
Does the patch below work for you?
From: Randy Dunlap <rdunlap at infradead.org>
When $DEPMOD is not found, only print a warning instead of exiting
with an error message and error status.
Warning: 'make modules_install' requires /sbin/depmod. Please install it.
This is probably in the kmod package.
../scripts/depmod.sh: line 44: /sbin/depmod: No such file or directory
make: *** [/home/rdunlap/lnx/lnx-418/Makefile:1244: _modinst_post] Error 127
