Re: unixodbc: no ??

At the moment I've got loose ends with this 'unixODBC-devel' package because:

- I can't find mention of it in the freeTDS documentation. If this is official 
and definitely needed then it's got to be somewhere in the documentation? 
Unless the '-devel' suffix belongs to standard Linux common knowledge and its 
necessity assumed to be known? 

- I've found a resource where to obtain 'unixODBC-devel':
http://rpm.pbone.net/index.php3/stat/4/idpl/11368942/dir/opensuse/com/unixODBC-
devel-32bit-2.2.12-93.1.x86_64.rpm.html
but the 'Content of RPM:' doesn't list sql.h

- there is otherwise another location to get unixODBC-devel:
http://sourceforge.net/projects/unixodbc/files/
as linked to by http://www.unixodbc.org/download.html, but its last update is 6 
years ago (2005) so perhaps not right place to look at?

- after having dowloaded a fresh standard unixODBC-2.3.0, I see that it has 
sql.h under include/. The odbc_inst utility is responsive so I 'think' that the 
installation of unixODBC-2.3.0 was successful despite a number of confest.c 
errors in its config.log, but I'm not familiar enough with this.

Can we bypass unixODBC altogether? I've read a number of times that it's 
recommended but not essential. I had freeTDS tsql working without unixodbc, 
perhaps I can hook it to DBD::ODBC directly?
