trying to build pigeonhole v0.4.3 sources on CentOs 6.5 - error while executing 'make'

[Wim Paulussen]

Hello all, 

I am trying to build pigeonhole from source but get the following (only
error output) : 

../../src/lib-sieve/.libs/libdovecot-sieve.so: undefined reference to
`mail_get_backend_mail'
collect2: ld returned 1 exit status
make[3]: *** [sievec] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2 

Output further shows following warning : 

ieve-actions.c:515 implicit declaration of function
'mail_get_backend_mail' 

dovecot -n :
