Hi,
Since there's only vanilla version of PD available for ubuntu 11.04 on beagleboard xM I tried to compile the mrpeach OSC externaly myself. I'm really far from being an experienced person with this stuff but this might help someone.
I browsed the internet to find the solution and i found some tips mainly at:
http://puredata.hurleur.com/sujet-4137-compiler-flags-building-external-darwin and http://puredata.hurleur.com/sujet-5114-xmix-announce
#!/bin/sh
mkdir src
mkdir out
compile()
{
echo "Compile ${1} with additional $2 flags"
gcc -I /usr/include/pd/ -std=c99 -DPD -O3 -Wall -W -Wshadow -Wstrict-prototypes -Wno-unused -Wno-parentheses -Wno-switch -DMUUG_INTERPOLATE=1 -DMUUG_TILDE_TABLE_SIZE=512 -fPIC ${2} -o out/${1}.o -c src/${1}.c
ld -shared -o out/${1}.pd_linux out/${1}.o
strip --strip-unneeded out/${1}.pd_linux
rm out/*.o
}
BASEURL="http://puredata.info/Members/martinrp/OSCobjects/"
FILENAME="routeOSC"
wget ${BASEURL}${FILENAME}.c/at_download/file -O src/${FILENAME}.c
compile ${FILENAME}
FILENAME="packOSC"
wget ${BASEURL}${FILENAME}.c/at_download/file -O src/${FILENAME}.c
compile ${FILENAME} "-fno-strict-aliasing"
FILENAME="unpackOSC"
wget ${BASEURL}${FILENAME}.c/at_download/file -O src/${FILENAME}.c
compile ${FILENAME} "-fno-strict-aliasing"
sudo mkdir /usr/lib/pd/extra/mrpeach
sudo cp out/packOSC.pd_linux out/routeOSC.pd_linux out/unpackOSC.pd_linux /usr/lib/pd/extra/mrpeach
After the script is executed pd has to be started with the correct path defined. In my case it's:
pd -nogui -path /usr/lib/pd/extra/mrpeach/ -open patch.pd
I don't know if i've done all of this the correct way but it seems to work for me. The routeOSC block does not return "error: ... couldn't create" message so i assume it works fine.
Now i have to find a way to load udpreceive block 
Cheers!
