FreeBSD5.4下安裝mod_deflate不成功，怎么解決啊？

roadli

在一臺(tái)FreeBSD5.4上安裝了Apache 2.0.54
想再裝個(gè)mod_deflate來實(shí)現(xiàn)內(nèi)容的壓縮，但是通過apxs安裝卻報(bào)錯(cuò)
代碼:

1. ----------------------------------------------------------------------
   
2. Libraries have been installed in:
   
3.   /usr/local/apache2/modules
   
4. 
   
5. If you ever happen to want to link against installed libraries
   
6. in a given directory, LIBDIR, you must either use libtool, and
   
7. specify the full pathname of the library, or use the `-LLIBDIR'
   
8. flag during linking and do at least one of the following:
   
9.   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
   
10.     during execution
    
11.   - add LIBDIR to the `LD_RUN_PATH' environment variable
    
12.     during linking
    
13.   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
    
14. 
    
15. See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages.
