Compiling issue

I'm running Ubuntu 10.10 and having a couple of issues. I've got both options for the toolchain work, only one is in the path at a time while testing. With one of them it seems to compile fine: I can use ./osmocom with something like hello world and this works. However when I go to look at layer23 the binary has not been compiled and I have this error in the conf.log: configure:3833: checking for gps_waiting in -lgps configure:3858: gcc -o conftest -g -O2 conftest.c -lgps >&5 /usr/bin/ld: cannot find -lgps collect2: ld returned 1 exit status configure:3858: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "" | #define PACKAGE "layer23" | #define VERSION "0.0.0" | /* end confdefs.h. */ I'm sure most of these are environment error but wanted to check. In the update-libosmocore.sh I get an error that git-subtree doesn't exist. I found git subtree as a third party install that was not in the documentation but it's command is git subtree versus being git-subtree. Any thoughts would be appreciated.
