Hello again,

I'm (still) trying to build sage on cygwin64 using the /u/jpflori/cygwin64 
branch from trac. I've run into quite a few errors but I've been able to 
fix them usually by following the wiki. However, I've run into a strange 
problem

The problem is that R fails while building one of its packages (grDevices) 
with the message:

byte-compiling package 'grDevices'
Warning in solve.default(rgb) :
  unable to load shared object 
'/home/jwpilly/sage/local/var/tmp/sage/build/r-3.0.2.p1/src/modules//lapack.dll':
  *No such file or directory*
Error in solve.default(rgb) : LAPACK routines cannot be loaded
Error: unable to load R code in package 'grDevices'
Execution halted
../../../share/make/lazycomp.mk:7: recipe for target 
'../../../library/grDevices/R/grDevices.rdb' failed
make[7]: *** [../../../library/grDevices/R/grDevices.rdb] Error 1

As you can see, the build script complains that there is no such file 
" 
'/home/jwpilly/sage/local/var/tmp/sage/build/r-3.0.2.p1/src/modules//lapack.dll'"
 
even though in the screenshot, you can see that there clearly is a file 
named "lapack.dll" at that path in windows explorer. I noticed that the 
file path contains a double forward slash, but I thought in linux this 
resolves to a single slash? Anyway, this strange bug is preventing sage 
from successfully building.

Any help is appreciated and thanks in advance
