[syslog-ng]missing flex?

[syslog-ng@lists.balabit.hu]

hi,
i'm trying to install syslog-ng1.6.2 with libol0.3.13.
libol works fine - my problem is syslog-ng. i get the error
below after 'make'. i thought flex was missing but after
installing flex i got the same error.
i read in the syslog-ng archive about a similar problem
and someone wrote that the problem ist the line "LEXLIB"
in the "src/Makefile" which should be set to "-lfl" but i don't
know what i have to change the line to.
my line looks like:
"LEX = /usr/local/src/syslog-ng/missing flex"

any suggestions?
