Package check issue: Rprofile.site is not used

Dear R-users,

I am having some issues with a package I am working on (using R 2.12.1 in a
Linux environment) and would like to have your opinions/advises. My package
- let's call it mypackage for the purpose of this email - passes all checks
of R CMD check, except for the following failure message:

Error : .onLoad failed in loadNamespace() for 'mypackage', details:
   call: source(file = options()$my_path, local = TRUE)
   error: invalid connection
Error: package/namespace load failed for 'mypackage'
Execution halted

The context is the following:

1- /usr/lib/R/etc/Rprofile.site contains the following line of R code:
options(my_path='/some/path/
to/myfile.txt')

2- mypackage has a NAMESPACE, and a .onLoad function is included in a zzz.R
file. Its content is the following:

.onLoad<- function(libname, pkname) {
   # print(options()) # for testing
   myf()
}

3- myf is a function distributed with mypackage. At one point of its
execution, this function tries to source /some/path/to/myfile.txt using the
following call: source(file = options()$my_path, local = TRUE)

When I start as R session and call 'options()$mypath', I get the expected
output: '/some/path/to/myfile.txt'. When I uncomment the 'print(options())'
line in .onLoad and try a R CMD check, mypath does not appear as a level of
options(). Overall, it looks like my Rprofile.site is not used when R CMD
check is run. Is there a way I could request R to use my Rprofile.site
during a package check?

Thank you in advance.

Sebastien
