Building problem on FreeBSD 8.1

[Donald Allen]

On a FreeBSD 8.1, I've downloaded the 2.4 tarball. When I run 'configure', I
get

checking for gzopen in -lz... yes
configure: External QOF Disabled.  Using Internal QOF Code.
checking dbi/dbi.h usability... no
checking dbi/dbi.h presence... no
checking for dbi/dbi.h... no
configure: error: Unable to find dbi/dbi.h

But

dca at octavian:/usr/home/dca/Software/Gnucash/gnucash-2.4.0$ find /usr/local
-name dbi.h -print
/usr/local/include/dbi/dbi.h
dca at octavian:/usr/home/dca/Software/Gnucash/gnucash-2.4.0$

I probably could fix this with a symlink in /usr/include, but isn't this
what configure is for, to understand the configuration and generate the
makefiles accordingly? The BSDs, unlike Linux, tend to put installed
packages in /usr/local, so I'm guessing this would be a problem on OpenBSD
and NetBSD as well. Perhaps I'm missing something here, so I thought I'd
check with all of you before trying the symlink hack.
