A mistake in perl

[fly19992020]

When I compile it, it says:

Making all in .
make[1]: 进入目录“/d/gnuaspell/aspell”
/usr/bin/perl ./gen/mk-static-filter.pl ./modules/filter/url-filter.info ./modules/filter/email-filter.info ./modules/filter/tex-filter.info ./modules/filter/sgml-filter.info ./modules/filter/markdown-filter.info ./modules/filter/html-filter.info ./modules/filter/context-filter.info ./modules/filter/nroff-filter.info ./modules/filter/texinfo-filter.info
Invalid general key in ./modules/filter/tex-filter.info on line 2 at ./gen/mk-static-filter.pl line 54, <OPTIONFILE> line 2.
make[1]: *** [Makefile:2289：gen/static_filters.src.cpp] 错误 255
make[1]: 离开目录“/d/gnuaspell/aspell”
make: *** [Makefile:1726：all-recursive] 错误 1

and so on
