Ok, I have some clues. I'm using this enviroment variables:

export CFLAGS="-Os -arch i386 -arch x86_64"
export PG_CPPFLAGS="-arch i386 -arch x86_64"
export SHLIB_LINK="-arch i386 -arch x86_64"
export LDFLAGS="-arch i386 -arch x86_64"

And the error I get is ld: symbol(s) not found for architecture i386

The symbols not found are some lwgeom functions. Apparently, they're
not constructed for i386 arch.

Here, the log created by make:
http://dl.dropbox.com/u/61566717/output/make_output.log

If I remove the x86_64 arch from the enviroment vars (even when my
processor is a 64bits one):

export CFLAGS="-Os -arch i386"
export PG_CPPFLAGS="-arch i386"
export SHLIB_LINK="-arch i386"
export LDFLAGS="-arch i386"

I get ld: symbol(s) not found for architecture x86_64

With the same symbols. Now they're not constructed for x86_64 arch.

Here, the log created by make:
http://dl.dropbox.com/u/61566717/output/make_i386.log

But if I do the opposite, and I try to compile just for x86_64 arch :

export CFLAGS="-Os -arch x86_64"
export PG_CPPFLAGS="-arch x86_64"
export SHLIB_LINK="-arch x86_64"
export LDFLAGS="-arch x86_64"

I get again: ld: symbol(s) not found for architecture i386

Here, the log created by make:
http://dl.dropbox.com/u/61566717/output/make_x86_64.log

Checking the makefile for lwgeom library, I don't see anything that
can force to compile against one architecture or another.

What's happening? How does PostGIS choose the architecture to compile
for? Should I define other enviroment vars?

Thanks in advance, and best regards
