 Dear Allin,
 first of all thanks for implementing the libsvm program into gretl!
 I just tried to test it on my xubuntu 17.04 linux machine. I used the shell 
 script build.sh to install the libsvm libraries. It ran through without any 
 issues. The following directories and files were set up:
 /usr/local/include/libsvm/svm.h
 /usr/local/lib/libsvm.so
 /usr/local/lib/libsvm.so.2
 /usr/local/lib/gretl-gtk2/svm.la
 /usr/local/lib/gretl-gtk2/svm.so
 /usr/local/bin/svm-predict
 /usr/local/bin/svm-train
 /usr/local/bin/svm-scale
 After running the shell script, I recompiled gretl using the --with-libsvm 
 option. However, I obtain the following error message when running your first 
 example script "Listing 1"
 <output>
    Failed to load plugin: /usr/local/lib/gretl-gtk2/svm.so
    Couldn't load plugin function
    Error executing script: halting
    > series svmpred = svm(L, parms)
 </output>
 even though the smv.so file is in the directory. 
What does
ldd /usr/local/lib/gretl-gtk2/svm.so | grep svm
say? And is /usr/local/lib indexed by ldconfig?
