compiling GRUB 1.93 on OpenBSD

[Marcos Latas <carvalholatas@sapo.pt>]

I have been trying to compile GRUB 1.93 on an OpenBSD machine to
create a port for it.

When I run ./configure the following message appears:

...
checking for __lzo_init_v2 in -llzo2... no
checking for __lzo_init_v2 in -llzo... no
checking for __lzo_init2 in -llzo... no
configure: error: LZO library version 1.02 or later is required


I have lzo-1.08 installed. I suppose GRUB is looking in the wrong
place for it. The lzo files are located on the following places:

/usr/local/include/lzo1.h
/usr/local/include/lzo16bit.h
/usr/local/include/lzo1a.h
/usr/local/include/lzo1b.h
/usr/local/include/lzo1c.h
/usr/local/include/lzo1f.h
/usr/local/include/lzo1x.h
/usr/local/include/lzo1y.h
/usr/local/include/lzo1z.h
/usr/local/include/lzo2a.h
/usr/local/include/lzoconf.h
/usr/local/include/lzoutil.h
/usr/local/lib/liblzo.a
/usr/local/lib/liblzo.la
/usr/local/lib/liblzo.so.1.0
/usr/local/share/doc/lzo/LTEST.TXT
/usr/local/share/doc/lzo/LZO.FAQ
/usr/local/share/doc/lzo/LZO.TXT
/usr/local/share/doc/lzo/LZOAPI.TXT

I suppose I have to change something in configure.ac, and then run
autoconf on it to produce the configure file. Could anyone help out?

Thank you very much for your time.
