[R-SIG-Mac] Problem with GSUB in PEIP

You may want to report to the maintainer - the GSVD sources have the following which is completely broken:

function (A, B) 
    SS = Sys.info()
    ssysname = SS[[1]]
    if (ssysname == "Linux") {
        lpath = paste(R.home(), "/lib/libRlapack.so", sep = "")
    else {
        lpath = paste(R.home(), "lib/i386/libRlapack.dylib", 
            sep = "")

It seems like the author failed to use the proper flags for linking LAPACK and then tried to hack around it in a horrible way that doesn't really work.

I suppose this happens when you don't even have a single test that a particular function works otherwise CRAN checks would not allow it in...

When I do “sos(‘gsvd’) only a few routines show, up, one is in the package PEIP.  I have installed the package PEIP (from binary), and the error below should be reproducible because it is not a function of my data:
>>> junk<-GSVD(Yf,Yp)
