There's no reason to believe that this problem relates to the kernel,
so installing another kernel will probably not help much.  I'd guess
that you have a directory permission problem.  Check these:

$ ls -ld /usr/bin /bin /usr/libexec
drwxr-xr-x  2 bin  bin  1024 Feb  1 15:41 /bin
drwxr-xr-x  2 bin  bin  6144 Feb  1 15:53 /usr/bin
drwxr-xr-x  5 bin  bin  1024 Feb  1 15:53 /usr/libexec

Reinstalling a complete operating system is overkill for just about
any problem you might have.
