Strange behavior of 'exists' function. Need help with Makefile.

[Yevgen Krapiva]

Hi guys, 

I'm trying to create my own port. I'm stucked with the following
Makefile:

PORTNAME=      openjsip
PORTVERSION=   0.0.4
...
...
MY_FILE=       proxy.properties

do-check: 

	#FIRST TEST
.	if !exists(/usr/local/share/openjsip/conf/proxy.properties)
		@${ECHO_MSG} ">> /usr/local/share/openjsip/conf/proxy.properties
doesn't exist"
.	else
		@${ECHO_MSG} ">> /usr/local/share/openjsip/conf/proxy.properties
exists"
.	endif
	
	#SECOND TEST
	@${ECHO_MSG} ">> DATADIR=${DATADIR}"

.for f in ${MY_FILE}
.	if !exists(${DATADIR}/conf/${f})
		@${ECHO_MSG} ">> File ${DATADIR}/conf/${f} doesn't exist"
.	else
		@${ECHO_MSG} ">> File ${DATADIR}/conf/${f} exists"
.	endif
.endfor


I'm trying to make script to check the existence of proxy.properties
file.
The first test works well while to other one (with the use of 'for')
doesn't.
Can you help me, I don't understand why the second test fails.
