After this, the build configure script didnt work:

checking whether dlsym() requires a leading underscore in 
symbol names... ./configure: line 72061: syntax error near 
unexpected token `_LT_AC_TRY_DLOPEN_SELF('
./configure: line 72061: `_LT_AC_TRY_DLOPEN_SELF('


I use libtool 1.4.2 if this helps ...
