No such problem here. grub-install is a simple shell script that
will eventually run the grub-binary. Your ktrace command only
traces the shell, you need options -i -d or just ktrace the
grub binary itself.

Tracing the grub binary here yields:

    66      1 ktrace   EMUL  "netbsd"
    66      1 ktrace   RET   ktrace 0
    66      1 ktrace   CALL  execve(0x7f7fffffd590,0x7f7fffffdaa0,0x7f7fffffdab0

This is

NetBSD pussyfoot 4.99.64 NetBSD 4.99.64 (PUSSYFOOT) #1: Fri Jun  6 22:44:04 
CEST 2008  
mlelstv@henery:/home/netbsd-current/obj.amd64/home/netbsd-current/src/sys/arch/amd64/compile/PUSSYFOOT
 amd64

The kernel is built with COMPAT_NETBSD32 and EXEC_ELF32 and the
following packages are installed:

netbsd32_compat40-extras-4.0
netbsd32_compat40-4.0
grub-0.97nb8

grub is a 32bit package built for netbsd-4.

-r-xr-xr-x  1 root  wheel  131188 May 15 09:59 /usr/pkg/sbin/grub

The system will not load the binary when the 32bit ld.elf_so is
missing. Then ktrace shows:

   541      1 ktrace   CALL  execve(0x7f7fffffd570,0x7f7fffffda80,0x7f7fffffda90
)
   541      1 ktrace   NAMI  "/usr/pkg/sbin/grub"
   541      1 ktrace   NAMI  "/emul/netbsd32"
   541      1 ktrace   NAMI  "/emul/netbsd32/usr/libexec/ld.elf_so"
   541      1 ktrace   NAMI  "/usr/libexec/ld.elf_so"
   541      1 ktrace   RET   execve -1 errno 8 Exec format error
