I know nothing about Solaris or what might be causing this problem,

and then put something like
R --vanilla< TestPackages.R> TestOutput.txt
at the end of the shell script that installs R, it will fail if any
installed R package fails to load properly and something informative
will be written to TestOutput.txt .

Upon reading the ticket more closely, it seems that maybe the problem
is that some packages are not even installed correctly, in which case
the above would be insufficient because it only tests correctly
installed packages. So, if you know that the Recommended R packages
(and perhaps some others) are supposed to be installed with Sage, then
you could hardcode those in the TestPackages.R script.
packages<- c("Matrix", "grid") # add more packages as necessary
for(i in seq_along(packages)) stopifnot(require(packages[i],
character.only = TRUE)

Given actually reading in these 6 libraries takes very little time, it would not
seem unreasonable to me to make a test that they actually import properly part
of the normal doctests that people run each time people test Sage. Any
reoccurring problem is far more likely to be found there, than by setting
SAGE_CHECK=yes, where its simply not practical to run that on the SPARC hardware
we have available. Building on 't2' already takes over 24 hours, though that
should be reduced dramatically soon.
If reading such a library took a long time, I could see a more reasoned argument
for not doing so. But even on my 10 year old workstation, it does not take long
to load an R library.
