R SIG Debian - Jan 2008 - problems building and installing some packages in 'unstable'

Hi,

I'm keeping a Debian unstable system, and recently found 2 problems:

1) building a package (R CMD build diveMove, available from CRAN)
depending on KernSmooth fails with:

---<---------------cut here---------------start-------------->---
Loading required package: KernSmooth
Error in dyn.load(file, ...) : 
  unable to load shared library
'/usr/lib/R/library/KernSmooth/libs/KernSmooth.so':
  libRblas.so: cannot open shared object file: No such file or directory
---<---------------cut here---------------end---------------->---

Needless to say, the package built fine until about 2 weeks ago and no
changes to the source have been made.

2) Installing a package (install.packages("tripEstimation")) requiring
mgcv fails with a similar message:

---<---------------cut here---------------start-------------->---
Loading required package: mgcv
Error in dyn.load(file, ...) : 
  unable to load shared library '/usr/lib/R/library/mgcv/libs/mgcv.so':
  libRblas.so: cannot open shared object file: No such file or directory
---<---------------cut here---------------end---------------->---

Interestingly, the shared libraries (KernSmooth.so and mgcv.so) do exist
at the specified path.  However, libRblas.so is nowhere to be found.

I've exchanged a few emails with Dirk Eddelbuettel, confirming that the
missing libRblas.so is expected in AMD64.

Are others following 'unstable' in AMD64 having the same problem?

For what it's worth, and given the brandnew sources on CRAN, I just updated
the Debian packages 
	r-cran-vr		## VR
	r-cran-kernsmooth	## KernSmooth
	r-cran-sandwich		## sandwich
	r-cran-rodbc		## RODBC
in the 'pbuilder' chroot environment (ie a pristine Debian unstable
setting
with no manual configuration whatsoever).  No issues.

So I have no idea where the desire to link with libRblas.so comes from, which
I why I suggested to Seb to ask here. If anybody, in particular amd64 users
of Debian unstable, has a clue, please share it with us.

Thanks, Dirk

Three out of two people have difficulties with fractions.

Hi again,

I should add that installation of the Debian packages r-cran-kernsmooth
and r-cran-mgcv proceeded without any problems.  It's just building and
installing packages requiring those (and possibly others) that are
giving the error.
