when i want install ORBit2-2.10.0 after ./congigure i have an error: "
DL-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libIDL-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libIDL-2.0' found
configure: error: Library requirements ( libIDL-2.0 >= 0.7.4 glib-2.0 >= 2.0.0 gobject-2.0 >= 2.0.0 gmodule-2.0 >= 2.0.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them."
I installed the new libIDL (0.8.3) from http://ftp.gnome.org/pub/gnome/sources/libIDL/0.8/
