process hangs when converting sgml documentation to PDF

Hi,

I tried to get a PDF version of the pgsql
documentation. the process i used is as follows

$ cd $PGSQL_ROOT
$ ./configure
$ cd $PG_ROOT/doc/src/sgml
$ gmake postgres.pdf

the outpout i get is as follows :

LC_ALL=C "/usr/bin/perl" /usr/bin/collateindex.pl -f
-g -o bookindex.sgml -N
{ \
echo "<!entity version \"8.0.3\">"; \
echo "<!entity majorversion \"`expr 8.0.3 :
'\([0-9][0-9]*\.[0-9][0-9]*\)'`\">"; \
} >version.sgml
"/usr/bin/perl" ./mk_feature_tables.pl YES
../../../src/backend/catalog/sql_feature_packages.txt
../../../src/backend/catalog/sql_features.txt >
features-supported.sgml
"/usr/bin/perl" ./mk_feature_tables.pl NO
../../../src/backend/catalog/sql_feature_packages.txt
../../../src/backend/catalog/sql_features.txt >
features-unsupported.sgml
openjade -D . -c
/usr/share/sgml/docbook/dsssl-stylesheets/catalog -d
stylesheet.dsl -t tex -V tex-backend -i output-print
-V texpdf-output -o postgres.tex-pdf postgres.sgml

and that's it, the prompt never comes back.

Can anybody please tell me why the process hangs up,
how can I get the PDf version from the sgml
documentations, using gmake.

thank you

Saquib
