I am puzzled by why you are seeing this message, especially if you are 
seeing it many times. I need more context to see why you are getting 
this message.

This is an error message that should only be generated if you try to 
load lib(eplex) into a running ECLiPSe, and you don't have eplex built 
correctly. I am not sure where the build process will try to load eplex, 
particularly if configure did not find any solvers for eplex -- which I 
assume is what happened in your case since you have not set 
ECLIPSETHIRDPARTY. In this case, the make should not try to build eplex 
at all.

Strictly speaking, you don't need any third party packages (the ones 
that go into the ECLIPSETHIRDPARTY directory) to build a basic version
of ECLiPSe. You are strongly recommended to have GMP or GMP-compatible 
library for bignums, because one (I think) library -- ic -- cannot be 
compiled by the restricted ECLiPSe compiler. I don't think you need Tcl 
to build ECLiPSe, but without Tcl, the GUI version of ECLiPSe 
(TkECLiPSe) would not be available.

For the other packages, you don't need them unless you want to use a 
library that need/interface to them, e.g. one of the supported  MP 
solver for eplex.

Note that the configure script will only search for 4.1 and 4.2 versions 
of GMP, as the license for GMP changed from an earlier version of LGPL 
to version 3 LGPL. These are rather old versions of GMP, and it is 
unlikely that the version you have in 10.8 will be one of this. We 
haven't tried newer versions of GMP because we have been told that we 
cannot use any software that has version 3 of LGPL, but my guess is that 
this restriction does not apply to you if you compile ECLiPSe yourself, 
but you probably need to modify the configure script.

However, as stated in the Setup guide, we recommend that you use MPIR 
(the version you could use is mentioned there, as MPIR has also gone 
LGPL 3.0, but the older version with LGPL 2 is still readily available 
because it is not LGPL 3.0)
