I've got the source and then I try and compile it using:
./configure --enable-server --with-mysql --with-net-snmp --with-libcurl

i get the following error:

./configure: line 10516: syntax error near unexpected token `IKSEMEL,iksemel,'
./configure: line 10516: ` PKG_CHECK_MODULES(IKSEMEL,iksemel,'

Since I'm not compiling using the with-jabber option I've edited the configure file and changed to :

if test "x$_libiksemel_with" != x"no"; then
if test "$_libiksemel_with" = "yes"; then
PKG_CHECK_MODULES(IKSEMEL,iksemel,

found_iksemel="no"
found_jabber="no"
else

Which seems to have fixed the problem and i've compiled the source successfully.
