Bingo. Your Postfix software is not properly installed. My Postfix 3.6.4
"master" executable does not have a "var_compat_level" symbol:
# objdump -T /usr/libexec/postfix/master | grep compat_level
0000000000000000 DF *UND* 0000000000000000 Base
compat_level_from_string
0000000000000000 DO *UND* 0000000000000000 Base compat_level
and correspondingly in libpostfix-global we see:
# objdump -T /usr/lib64/postfix/libpostfix-global.so | grep compat_level
0000000000034be0 g DF .text 000000000000008d Base
compat_level_relop_register
0000000000034760 g DF .text 0000000000000150 Base
compat_level_from_string
00000000000349f0 g DF .text 00000000000000c5 Base
compat_level_from_numbers
000000000004e7c0 g DO .bss 0000000000000008 Base compat_level
0000000000034ac0 g DF .text 0000000000000120 Base
compat_level_to_string
Your "master" executable appears to be from an older Postfix version.
