[Simh] Compile error 1 SIMH-V3.7

[Michael Copini]

Running a Pentium 4 machine with 1GB of memory with CentOS 4.5.
I downloaded the libpcap and the simh
did a ./configure and make + install on libpcap (no errors) unzipped
simh -a into a SIMH directory created a BIN under SIMH

The gmake command exits with an Error 1.

[mcopini at MiDi-Simh SIMH]$ gmake USE_NETWORK=1 BIN/vax gcc -std=c99 -O2
-U__STRICT_ANSI__ -g -lm -D_GNU_SOURCE -I . VAX/ vax_cpu.c
VAX/vax_cpu1.c VAX/vax_fpa.c VAX/vax
/tmp/cc3WMZQ6.o(.text+0x58): In function `sim_os_ms_sleep_init':
/home/mcopini/SIMH/sim_timer.c:299: undefined reference to
`clock_getres'
collect2: ld returned 1 exit status
gmake: *** [BIN/vax] Error 1
[mcopini at MiDi-Simh SIMH]$

Any help would be appreciated.
