[Openswan Users] Compile errors

[Openswan]

Hello,

I'm a new to openswan so please be patient..

My config:
-Slackware 10,  kernel 2.6.9

When compiling from source (openswan-2.2.0.tar) via "make programs" I get 
the following errors:

make [2] Entering directory '/usr/src/openswan-2.2.0/programs/starter'
cc -DNAT_TRAVERSAL -DVIRTUAL_IP ....
parser.l: in function 'parser_y_error':
parser.l:61: error: conflicting types for 'yytext'
lex.yy.c:483:error: previous declaration of 'yytext'
lex.yy.c:in function 'yylex'
leaving dir /usr/src/openswan-2.2.0/programs/starter

Any ideas?

Appreciated
Stefan
