[BioC] Loading problem with Rlibstree and microRNA packages on Mac OS X 10.4

[Luo Weijun]

Dear all,
I called microRNA package when I tried rtracklayer package on a Mac OS X 10.4 machine. Errors produced when loading the depended package Rlibstree (see below).
I tried installed Rlibstree alone from binaries or source, both failed. Error messages (see below). suggested that R_newStringSet and R_stringSetAdd functions (in stree.c file) had problem when passing argument 1 of 'lst_string_new'. This seems to be consistent with the loading error message, but I am not sure what does it mean. Could anybody help or give any hints. Thanks a lot!
