[Evolution] Compilation error on PCLinuxOS

[Neverstopdreaming <neverstopdreaming gmail com>]

Hi all,
I'm trying to update our 2.6 evolution to latest 2.8.1 but I encounter
this error on compilation.
Does anyone have an idea about it?
gcc is 3.3.1
I already complied and installed all the other latest evo stuff
(gtkhtml, libsoup and evo-data-server) with success.

e-tree-memory.c: In function `e_tree_memory_node_insert':
e-tree-memory.c:507: warning: implicit declaration of function `g_slice_new0'
e-tree-memory.c:507: error: syntax error before "ETreeMemoryPath"
e-tree-memory.c: In function `child_free':
e-tree-memory.c:582: warning: implicit declaration of function `g_slice_free'

make[3]: *** [e-tree-memory.lo] Error 1

thanks
best regards
