[yocto] Mpich and yocto ?

[Riko Ho]

Dear Yocto Team Member,

I tried to compile icecream on the master node, but here's the messages 
I got, any ideas ?

=====

Making install in services
make[1]: Entering directory '/home/bianchi77/icecream/services'
make[2]: Entering directory '/home/bianchi77/icecream/services'
  /bin/mkdir -p '/usr/local/lib'
  /bin/bash ../libtool   --mode=install /usr/bin/install -c libicecc.la 
'/usr/local/lib'
libtool: install: /usr/bin/install -c .libs/libicecc.lai 
/usr/local/lib/libicecc.la

Thanks
