[sr-dev] modules/utils.so: undefined symbol: curl_easy_getinfo

i just built kamailio on debian squeeze from master and when i tried to start it, i got: 0(19113) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib/sip-proxy/modules/utils.so>: /usr/lib/sip-proxy/modules/utils.so: undefined symbol: curl_easy_getinfo built when fine without errors. when i look deb/squeeze build-depends, it lists libcurl3-openssl-dev however, debian squeeze does not have that package. instead it has libcurl4-openssl-dev: # apt-get install libcurl3-openssl-dev Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libcurl4-openssl-dev' instead of 'libcurl3-openssl-dev' libcurl4-openssl-dev is already the newest version. a week or so ago i didn't have this problem. any suggestions? -- juha
