 Packages are not an options, since I need a network wide installation 
 and there are certain differences between Solaris 8 (the version the 
 packages refer to) and Solaris 10.

+After some debugging I've found the cause for the bug. You are 
+passing -D_FILE_OFFSET_BITS to the configure script in libgc. As the 
+comment in the toplevel configure script states this may be a bad 
+idea. And it is a bad idea.
+
+The size of the prasmap struct (part of the procfs interface in 
+Solaris) depends on the size of off_t, which depends on 
+_FILE_OFFSET_BITS. This trashes the code that parses the page 
+information from proc.
+
+Solution: do not pass _FILE_OFFSET_BITS to libgc. What do you need it 
+for, anyways?
