asterisk users - Feb 2007 - Can't get asterisk to compile chan_zap (was "NewIssue")

(I apologize if this is a dupe, but I never saw my first copy)
I captured the output of ./configure and found the following lines:

<lines snipped>
checking zaptel/tonezone.h usability... yes
checking zaptel/tonezone.h presence... yes
checking for zaptel/tonezone.h... yes
<lines snipped>
checking for ZT_TONE_DTMF_BASE in zaptel.h... Yes
<lines snipped>

So it seems to be finding the /usr/include/zaptel directory and files fine.
Is there anything else I can do that might offer information that could help
track this problem down?

Thanks,
