ok, here's the deal.
i'm trying to install zexy 2.1. i'm using pd 0.41-1, on a macbook pro os x.4.11 with xcode.

i've put the zexy-2.1 folder in ~/Library/Application Support/Pd
i've changed the terminal directory to the src folder within this directory, and executed "./configure" successfully.

the problem comes in the next step. the linux install instructions say type "make" followed by "make install".

once i've run "make", it comes up with the following:
zexy.h:38:18: error: m_pd.h: No such file or directory

and from what i've read, m_pd.h is quite important. the terminal also displays lots of other error messages, mainly starting with:
a2l.c:XX:

i've also tried this command, which is stated in the install instructions:
"make -f makefile.darwin"

but it comes up with this:
make: makefile.darwin: No such file or directory
make: *** No rule to make target `makefile.darwin'. Stop.

this makes sense, as "makefile.darwin" is not included in the src directory (or anywhere in "zexy-2.1" for that matter)

i'm new to all this compiling malarkey, so any help on this matter would be greatly appreciated.

cheers

the solution:

with help from a programmer friend of mine, i've managed to solve this problem. it appears there are a few problems with the installation files included in the zexy 2.1 folder, when installing on os x. here's a guide to getting it working.

firstly download the zexy-2.1 source as well as the pd-0.41-1 source. i put both of these folders in: Users/your_username/Library/Application Support/Pd

find the file "m_pd.h" which is in the "pd-0.41-1/src" folder. copy this file to the "src" folder in the zexy-2.1 directory.

in terminal, change directory to the zexy-2.1 source folder. so if you put the 2 directories in the same folder as i did, type:
cd Library/Application\ Support/Pd/zexy-2.1/src
[enter]

then type:
./configure
[enter]

assuming Xcode is installed, this should run a number of commands, including creating a file called "Makefile" in the "zexy-2.1/src" folder. open this in textedit.

there will be a line which says something along the lines of:
PREFIX =/usr/local/...

change this line to look like this (assuming pd is installed in the applications folder):
PREFIX =/Applications/Pd-0.41-1.app/Contents/Resources

in the same way, alter this line:
LFLAGS = -bundle -bundle_loader /user/local/...

to look like this
LFLAGS = -bundle -bundle_loader /Applications/Pd-0.41-1.app/Contents/

save the file. in the terminal type:
make
[enter]

followed by:
make install
[enter]

that should be the terminal stuff out of the way. now open up pd, and in the startup preference window, type:
/Applications/Pd-0.41-1.app/Contents/Resources/extra/zexy
[apply -- ok]

restart pd. you should now be able to use all the zexy objects!
