Indeed.
Thinking this might be something simple for which I could provide a
patch, I tried to build from source, which failed thusly:
rm -f blib/arch/auto/SWISH/API/API.so
cc -shared -L/usr/local/lib API.o -o blib/arch/auto/SWISH/API/API.so
\
-L/usr/lib -lswish-e -lz -lm \
/usr/bin/ld: cannot find -lswish-e
collect2: ld returned 1 exit status
make: *** [blib/arch/auto/SWISH/API/API.so] Error 1
I believe the cause for this was that I had swish-e already installed,
but not swish-e-dev, so Makefile.PL could find libswish-e, but the
linker couldn't. Installing swish-e-dev resulted in an API.so linked
against libswish-e, but a package can't depend on already being
installed in order to build from source :)
Digging further, I removed swish-e and swish-e-dev, and started the
build again from scratch. This time I noticed in the perl section:
(chmod 755 swish-config;cd perl; env PATH=..:ATH SWISHSKIPTEST=1
SWISHIGNOREVER=1 /usr/bin/perl Makefile.PL INSTALLDIRS=vendor <
/dev/null \
&& /usr/bin/make OPTIMIZE="-Wall -g -fPIC -O2 -I../src/"
CC=gcc LD=gcc LD_RUN_PATH=)
Using swish-config found at [../swish-config]
Checking if your kit is complete...
Looks good
Note (probably harmless): No library found for -lswish-e
Writing Makefile for SWISH::API
That "probably harmless" bit seems to be precisely the source of harm.
I'm not that familiar with the guts of the debian package build process,
but I'd guess that one of two things needs to happen:
1) The "make install" part of swish-e needs to happen before the perl
build
2) The perl build needs to have an -rpath (or LD_RUN_PATH) sent to it to
find the libraries in the build folder
Hope this helps,
