[syslog-ng] errors running configure for incubator on Ubuntu 12.04

[Russell Fulton]

rful011 at secmontst01:~/src/syslog-ng-incubator$ ./configure 
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane… yes

[ snip ]

checking whether g++ accepts -g... yes
checking dependency style of g++... gcc3
checking for inline... inline
./configure: line 4534: syntax error near unexpected token `shared'
./configure: line 4534: `LT_INIT(shared dlopen)’

I have looked at configure and config.log to try and figure out what it is actually checking for.  ‘inline’ is to generic to google for :(

any ideas what is wrong?
