racd installation

Hi,
I am trying to install 'racd' package of Alexios to R 3.3.1 and come up
with the following error messages.
-----

 require(devtools)

Loading required package: devtools

install_bitbucket("alexiosg/racd")

** preparing package for lazy loading
Warning in rgl.init(initValue, onlyNULL) :
  RGL: unable to open X11 display
Warning: 'rgl_init' failed, running with rgl.useNULL = TRUE
Error : object 'as.vector' is not exported by 'namespace:Matrix'
ERROR: lazy loading failed for package 'racd'
* removing '/gpfs/software/R/3.3.1/gcc/lib64/R/library/racd'
Error: Command failed (1)

-----
How could I solve for these errors? By the way, when will the 'racd' could
be downloaded directly from CRAN?

Regards,
Trung
