​The link above didn't work for me, but when I tried installing with the
cpan shell, it grabbed the Geo-Shapelib package from here:​


​http://www.cpan.org/authors/id/A/AJ/AJOLMA/Geo-Shapelib-0.21.tar.gz

The shapelib package can be downloaded via the link above and extracted,
which creates a folder named Geo-Shapelib-0.21.  Normally the next step is
to issue "perl Makefile.PL" from a terminal inside the folder above.
However that bombed because the make file was looking in the wrong place
for the shapelib development files. My files are in
'/usr/lib/i386-linux-gnu', so in theory the command below should have
addressed that:

perl Makefile.PL --shapefile=/usr/lib/i386-linux-gnu

However, I still got the same error that it could not find the shapelib
files.  I ended up editing ​Makefile.PL - I believe it's line 18:

for (qw(/usr/lib /usr/lib/x86_64-linux-gnu /usr/local/lib)) {

new version:
for (qw(/usr/lib /usr/lib/i386-linux-gnu /usr/local/lib)) {

Then issuing "perl Makefile.PL", followed by changing to root and entering
"make install" completed the installation.  I did get a warning about a
dependent module not installed (Tree::R), but given it's a warning it may
not be an absolute requirement.

l did all of the above on an old 32 bit computer running Debian Jessie.  If
you are running a 64 bit version, perhaps Makefile.PL will work as is.  If
not, you'll have to edit it to tell it where to find your libshp.so file.

I don't have a gpx file I can try, though, so I don't know if the old 2006
script will work now that I have the Shapelib module installed.  You can
consider this a fallback in case you can't get gdal fixed.  :-)
