library not found for -lbundle1.o when installing python packages (ffnet, spacepy) on my mac

Question

I have the anaconda python distribution installed on my mac (10.9). I'm trying to install the ffnet package and the SpacePy package, but having trouble in doing so. Here is the error I get when doing sudo easy_install ffnet :

ld: library not found for -lbundle1.o
collect2: erreur: ld a retourné 1 code d'état d'exécution
ld: library not found for -lbundle1.o
collect2: erreur: ld a retourné 1 code d'état d'exécution

I have the same "library not found for -lbundle1.o" error when trying to install the spacepy package.

I do have the following file on my mac :

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/lib/bundle1.o

I have tried to make a symbolic link :

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/lib/libbundle1.o -> bundle1.o

in case the -lbundle1.o was looking for libbundle1.o and not bundle1.o and have the same error

Answer 1

I reinstalled the developper tools using the command :

xcode-select --install

which I found here

I had Xcode installed before I updated mountain lion to mavericks, and I guess something went wrong or that it is well known that one has to reinstall the developer tools after upgrading to Mavericks.... Anyway that solve the problem.
