[R-sig-Debian] problems building and installing some packages in 'unstable'

[Douglas Bates]

Check if the file $R_HOME/lib/libRblas.so exists. If so, use

ldd $R_HOME/lib/libRblas.so

to see what further shared objects it needs.

Then check

ldd $R_HOME/library/KernSmooth/libs/KernSmooth.so

It probably has a reference to libRblas.so that is unresolved when you
check outside of R.  Part of the R startup adds $R_HOME/lib to the
LD_LIBRARY_PATH (see the shell script $R_HOME/etc/ldpaths or
$R_HOME/etc${ARCH}/ldpaths)
