Works fine here on a few weeks old RELENG_7:

$ uname -rs
FreeBSD 7.0-BETA4-20071214
$ pkg_info | grep strace
strace-4.5.5        A portable process tracer
$ strace pwd
execve(0xbfbfdf6c, [0xbfbfe434], [/* 0 vars */]) = 0
__sysctl([...], 0xbfbfe18c, 0xbfbfe190, NULL, 0) = 0
syscall_477(0, 0x110, 0x3, 0x1000, 0xffffffff, 0, 0) = 0x28074000
munmap(0x28074000, 272)                 = 0
__sysctl([...], 0x2807077c, 0xbfbfe1f0, NULL, 0) = 0
syscall_477(0, 0x8000, 0x3, 0x1002, 0xffffffff, 0, 0) = 0x28074000
issetugid(0x2806a6cc)                   = 0
open("/etc/libmap.conf", O_RDONLY)      = -1 ENOENT (No such file or directory)
open("/var/run/ld-elf.so.hints", O_RDONLY) = 3
..
and so on.

Best regards
