I installed the acepack package under Linux (gcc 2.7.2, R-0.61.1).
Installation without problem. But

The first problem (not magically loading of the shared
library) is easy to fix. The zzz.R file in acepack/R is
----------------------------------------------------------
..First.lib <- function(lib, pkg) {
  library.dynam("acepack", pkg, lib)
  }
  
if (version$minor < "0.62")
    library.dynam("acepack")  
----------------------------------------------------------
but the correct test, at least the one which works on my machine,
should be
---------------------------------------------------------
if (version$minor < "62.0")
    library.dynam("acepack")
----------------------------------------------------------

Does someone here has some hints for the second (the segmentation
fault) ?
Thanks in advance.

ps1. I also tried to link the shared library with libf2c as
     suggested in the makefile but nothing changed.
     BTW, which version of libf2c?
ps2. The avas function works without any problems.
