[notmuch] Problem Building on OSX leopard 10.5.8

[Saptarshi Guha]

Hello,
Having given up on most email clients yet trapped by them, I came  
across notmuch.
Quite eager to build,

1.download xapian,

A suggestion :

In the INSTALL/README file, mention that xapian-config should be on path
and that it be called xapian-config.
When I installed the latest, it was installed in /usr/local/bin (not  
in my path)
at xapian-config-1.1

2. download gmime (no problem here)

3. Install talloc (the makefile has errors in it)


Problem Building notmuch:
I got this error:

lib/index.cc: In function ‘void  
_index_address_mailbox(notmuch_message_t*, const char*,  
InternetAddress*)’:
lib/index.cc:46: error: ‘strndup’ was not declared in this scope


Any ideas?
Thank you
Saptarshi
