   /u/gl/rdm/local/lib/swish-e/perl/SWISH/Filters/XLtoHTML.pm

I don't have Doc2html, Pdf2HTML, ID3toHTML, or XLtoHTML.
Wonder how that happened!  Well, let's try a re-install...

Well, no complaints, but no luck, either:

   % ls /u/gl/rdm/local/lib/swish-e/perl/SWISH//Filters
   Doc2txt.pm   XLtoHTML.pm

Looking closely at the install output, I see:

   make install
   Making install in filters
   Making install in SWISH
   /bin/bash ../../../swish-e-2.4.2/config/mkinstalldirs
     /u/gl/rdm/local/lib/swish-e/perl/SWISH
     /u/gl/rdm/swish-e/swish-e-2.4.2/config/install-sh -c
     ../../../swish-e-2.4.2/filters/SWISH/Filters/Doc2txt.pm
     /u/gl/rdm/local/lib/swish-e/perl/SWISH/Filters/Doc2txt.pm
     /u/gl/rdm/swish-e/swish-e-2.4.2/config/install-sh -c
     ../../../swish-e-2.4.2/filters/SWISH/Filters/Pdf2HTML.pm
      
/u/gl/rdm/local/lib/swish-e/perl/SWISH/../../../swish-e-2.4.2/filters/ 
SWISH/Filters/Pdf2HTML.pm
     /u/gl/rdm/swish-e/swish-e-2.4.2/config/install-sh -c
     ../../../swish-e-2.4.2/filters/SWISH/Filters/ID3toHTML.pm
      
/u/gl/rdm/local/lib/swish-e/perl/SWISH/../../../swish-e-2.4.2/filters/ 
SWISH/Filters/ID3toHTML.pm
     /u/gl/rdm/swish-e/swish-e-2.4.2/config/install-sh -c
     ../../../swish-e-2.4.2/filters/SWISH/Filters/XLtoHTML.pm
     /u/gl/rdm/local/lib/swish-e/perl/SWISH/Filters/XLtoHTML.pm

This makes me VERY suspicious.  The install paths for Pdf2HTML
and ID3toHTML look really odd.  So, I looked to see where they
might have landed:

   % du -a local | grep SWISH
   ...
   4       local/lib/swish-e/perl/SWISH/Filters/Doc2txt.pm
   8       local/lib/swish-e/perl/SWISH/Filters/XLtoHTML.pm
   ...
   8       local/lib/swish-e-2.4.2/filters/SWISH/Filters/Pdf2HTML.pm
   14      local/lib/swish-e-2.4.2/filters/SWISH/Filters/ID3toHTML.pm

This seems distinctly peculiar.  So, I tried:

   %  cp local/lib/swish-e-2.4.2/filters/SWISH/Filters/*.pm \
   local/lib/swish-e/perl/SWISH/Filters

This caused Pdf2HTML to be found.

In summary, I was having an installation problem, either because
I did something wrong or because there's a but in the Swish-e
installation machinery.  FYI, my configure script looks like:

:
# config_rdm - configure swish-e

VER='2.4.2'

./swish-e-$VER/configure        \
   --disable-shared               \
   --prefix=$HOME/local           \
   CPPFLAGS=-I$HOME/local/include \
   LDFLAGS="-R$HOME/local/lib -L$HOME/local/lib"

and $HOME is set to "/u/gl/rdm".

I looked at the Makefile, but it baffles me.  Perhaps someone
else can figure out what's going wrong...
